Do you know the difference between CRM and call center software?
A CRM system may be part of a contact center software stack, but by itself, it’s not enough to provide a personalized experience to your customers.
And siloed communication and a dozen hard-to-set-up integrations is a steep price to pay to get there. Instead, you should use a multichannel call center software solution.
A CRM helps businesses keep a digital record of customer interactions. Call center software enables companies to send, manage, and track messages and calls to customers.
It’s the first step to providing a modern, high-standard customer experience.
We will cover the differences between CRM and call center software in-depth in this post.
Let’s get started!

1) Big picture

Before we dive deep into the different features and use cases, let’s start with the big picture. What’s the actual difference in the definition and purpose of the two solutions?

What Is Call Center Software?

Call center software is a tool for managing and optimizing voice communications. Advanced call routing helps you manage and direct incoming calls.
Supervisors and managers get access to reports and live dashboards. They highlight call center performance in real-time. You also get features to track phone call stats and improve agent efficiency.
Separate call queues ensure each caller reaches the right department. This approach leads to less chaos and a happier customer. It’s the foundation of an efficient call center.

What Is CRM?

Customer Relationship Management (CRM) software helps companies track all customer interactions. It’s the ultimate source of all customer information.
CRMs can log phone numbers, purchases, refunds, marketing engagement, and many other touchpoints. It’s a complete digital customer history.
Customer service agents can fill out profiles with info from calls, emails, and other channels. A detailed customer support history gives each agent context on every customer. They can skip redundant questions and help callers faster.

And it’s not just suitable for agents. Managers can use call data and reports to track agent and call center performance.
And support isn’t the only area of your business it can help.
Sales teams can keep track of prospects across all stages of their pipeline.

2) Use cases

Call Center Software

Call center software improves agent productivity without reducing customer support quality. It plays a vital role in all call center campaigns, whether they are inbound or outbound.

• Inbound sales agents can use it for orders, billing issues, or sales over the phone or social media.
• Technical support teams can use it to track ticket progress and enable self-service options.
• Outbound call center software features include contact lists, lead management, and progressive dialers. They help your sales reps close more prospects, faster.

As your call center agents take on more responsibility, the focus moves away from phone calls. That’s the future.

CRM

By tapping into various data sources, a CRM documents your customer’s journey. It keeps track of everything, from the first touchpoint to the last.
These are a few primary use cases:

• Companies store in-depth profiles on prospects and leads.
• Sales reps update profiles when prospects or customers make a purchase.
• Customer service agents can keep a record of tickets, complaints, and requests. (Various CRM integrations come in handy here.)
• eCommerce stores can track relevant online user activity. (Such as product page visits, adding products to cart, etc.)

3) Key features

Call Center Software

• Analytics & Reporting: Dashboards highlight real-time data on individual agents and call center performance. From the rate of answered calls to the first response time, stay on top of key metrics.
• Computer Telephony Integration(CTI): CTI integrates phone and voice channels with business tools. It enables CRM integrations.
• Contact Center as a Service: Set up and deploy a full-featured, scalable contact center in the cloud. Solve customer questions from multiple touchpoints, including phone, email, social media, and text messaging.
• Call Queue: This feature places callers on hold when the line is busy and plays an automatic message.
• Call Recording: Record customer conversations in HD instantly through the cloud. With VoIP, it’s no longer a tedious process that requires special hardware. Supervisors/agents don’t need to do anything on-call to activate it.

That’s not all.
There are many more VoIP features in our call center software. Use them to level up your phone system service.

4) Front end vs. back end

CRMs Are Your Go-to Back-office Tools

A CRM is a complete database of your customer interactions. It logs what they purchased when they spoke with a support agent and more.
This customer data provides you with a high-level view of your business.
Agents can use it to find relevant information about your prospects and customers. Your business doesn’t use CRM solutions to interact with customers.
Sure, using CRM data to provide a personalized experience is possible. But a CRM is only as good as the data it collects.
It should be plugged directly into channels for sales/support. If not, you are relying 100% on human reporting.
Standalone CRM solutions often advertise integrations with communication software. But the reality is they tend to be faulty and limited in scope.

Call Center Software Directly Impacts Communications

Out of the two, a call center is the front-end solution. It changes how you interact with customers. You can use it to make and receive inbound calls and outbound calls.
Call center software directly impacts how customers experience your company:

• Interactive Voice Response (IVR) helps your customers find the right department when they call support.
• Call distribution policies lower average wait times.
• Call screening helps your callers reach their account managers more efficiently.
• An integrated dashboard tells the full customer service story across channels.

Setting up these processes leads to better customer experience. Managers apply these call center best practices to achieve massive results.

5) Cloud vs. on-premise

CRM

CRM tools have been around since before the internet. Twenty years ago, the market leaders were still on-site. Many enterprises even had custom-developed in-house solutions.
But times have changed. There are still options on the market, but few and far between.
Cloud-based solutions have taken over. They are more cost-effective and require no IT staff for oversight and management.
Any hosted solution is much easier to manage. Your company doesn’t have to worry about updates or database maintenance. There’s no need for a high-tech solution in your office.
And these aren’t the only benefits of moving to the cloud. Both sales and customer service CRM data will be available across offices throughout the country.

Call Center Software

Call centers used to use on-premise PBX (private branch exchange) and custom software. Getting it up and running was a big project, but once a solution was up, it became the beating heart of a call center.
A PBX helps distribute calls efficiently and streamlines call transfers and other collaboration. It ensures that customers wait as little as possible and get a more consistent level of service.
But in recent years, on-site call center software has started to become obsolete.
If you have an existing PBX, you can use SIP trunking to invigorate it and bring your call center into the 21st century.
But if you’re starting from scratch, you don’t need to install anything in your office except phones. Today, off-site, cloud-hosted PBX solutions provide all essential business phone features.
All you need in your office is an internet connection and a phone for each desk.
Your provider handles the nitty-gritty of your business communications — from VoIP calls and text messages to call recording and more.
With VoIP, you don’t even need landlines or phones — your agents can handle calls using a desktop or mobile app and a headset.

6) Core users

CRM

Small business owners often think CRM is a tool reserved for enterprises. But that’s no longer the case.
Today, core users include:

• SMBs with a long sales process. (Businesses that focus on B2B sales and high ticket items.)
• Real estate agents, insurance agents, and other businesses rely on leads.
• eCommerce stores that use data to provide personalized offers.
• Enterprises that want to use data to improve customer experience.

Call Center Software

All call centers rely on call center software. It doesn’t matter if it’s an inbound call center, outbound, or a blended call center.
Many companies without dedicated call centers also rely on the software.
For example:

• Small businesses that use phones for sales and service.
• Medium-large companies that handle service on many channels.
• eCommerce businesses that need to set up a virtual call center.
• Enterprises that want to integrate communication across all service channels.

7) Pricing & costs

Globally, on average, companies between 51-100 employees use 79 different SaaS applications. And an average employee uses 8 SaaS applications as part of their day-to-day responsibilities.
These software expenses can add up, so the pricing and running costs are essential to consider.

CRM

Industry-leading solutions charge as much as $75-$150/month per user. That’s thousands of dollars per year, even for a small business.
Nextiva’s customer service CRM is much more reasonable, with plans ranging from $20-$60/month per user. Switching can mean significant cost savings for small and medium businesses.
Our CRM integrates with our VoIP service, making it easy to stay on top of all voice communications.

Call Center Software

Open-source or pre-developed local solutions might seem like the winner, as there are no subscription costs. But you still have to pay phone bills every month to cover the landlines.
Nextiva’s inbound call center solution starts as low as $60/month per user. Plus, you get both VoIP phone service and the call center software as a package deal. Even our basic plan includes unlimited calling in the US, Canada, and Puerto Rico.
Hosted solutions are also much more scalable. With remote staffing capabilities, you have new options. You can cover rush hours without expanding staff or office space. Your call centers don’t even need physical locations.

8) CRM metrics vs. call center metrics

Customer service metrics are essential data points that help modern companies succeed. Each tool provides part of the picture.

CRM Metrics

CRM metrics focus on customers, sales, and revenue. The focus is on using the data to power sales teams to meet their goals.

• Conversion Rate: The percentage of leads or prospects that made a purchase.
• Repurchase Rate: The percentage of customers that return to buy another item.
• Retention Rate: The percentage of customers you keep over a set period.
• Sales Cycle Length: The average amount of time it takes to convert a prospect into a paying customer.

Call Center Metrics

Call center metrics to show the level of service your agents are providing your customers. From how long they wait, to how many interactions it takes to solve an issue. They give you the full picture.

• Customer Satisfaction Score (CSAT): A score calculated with automated surveys after service interactions.
• Average Wait Time: Same as FRT, but specifically for calls.
• Rate of Answered Calls: The percentage of incoming calls that your reps pick up before the caller hangs up.
• First Call Resolution Rate: The percentage of calls where agents fix the caller’s issue on the first try. (Your agents must register interactions in a CRM to track this data)

End Communication Silos with CRM + Call Center Software

Without VoIP, your business’ support and sales calls don’t happen over the internet. It can be hard to integrate this data with your existing CRM.
As a result, voice is often the support channel that gets left out. Other teams or team members don’t know about previous customer interactions.
The separation of channels is a significant customer support issue. Experts call this “siloed communication.”
The right call center software eliminates “communications silos” with a built-in CRM.
That’s what Nextiva’s unified customer service platform puts on the table. In the same dashboard, it offers true omnichannel support with voice, text messages, and helpdesk tools.
You get the best of both worlds with advanced call routing and CRM data handling features. Use a single interface to manage your customers. And starting at $20/month per user, it’s often cheaper than a CRM alone.

Voice over IP Overview

Voice over Internet Protocol, or VoIP for short, enables you to make low-cost phone calls over the internet.
You might often hear the terms “internet telephony” and “broadband phone service” when referring to the service, but these days VoIP is the standard terminology used among IT professionals.
After you set up a VoIP phone system, you can dial anywhere in the world and anyone can call you. The underlying technology makes talking to people over the phone as simple as sending a direct message over social media.

How does VoIP work? The answer depends on which method you’re using:

• IP Telephones: These devices operate in a similar fashion to traditional phone systems, but this time they plug straight into your computer. IP phones usually come with all the hardware and software needed to connect to your router or server.
• Computer-to-computer: With this approach, all you need is the right software and a decent sound card. If you have a headset and a microphone, you’re good to go.
• Analog Telephone Adaptor (ATA): An ATA adaptor allows you to plug your traditional telephone to your computer and make VoIP calls. It takes the analog signal from your traditional phone and converts it into digital data, which can then be transferred over the internet.

The main difference between ATA and IP is in the connectors. ATA uses traditional RJ-11 connectors, while IP telephones use RJ-45 connectors that can be plugged directly into an Ethernet port.
This image from a Quora post perfectly illustrates the difference:

The complexity of each approach listed above depends on whether you’re building an on-premise system or using a hosted service. We’ll explore the distinction between the two shortly.

1. The benefits of VoIP

Now you understand the basics of how VoIP works. The question is, why should you invest in it?
There are many benefits to VoIP, and the reasons to implement it will depend on your business structure, strategy, and goals.
Here are several of the common reasons that organizations and IT professionals invest in VoIP:

1. Costs: A reduction in hardware means fewer costs for setting up and maintaining your communications stack. Traditional landlines are expensive due to the limited number of lines available. This isn’t a problem when making calls over the internet, making it a cheaper approach.
2. Reliability: If the internet is down, does that mean you can’t make calls? Thanks to flexible call forwarding options, the answer is no. The same goes for weather interferences, or hardware and power outages.
3. Mobility: If you have a smartphone that can connect to the internet, you can make VoIP calls on the go. This is especially handy for remote teams, as it allows them to make calls from anywhere in the world. In the age of working remotely, a remote office phone system has your business covered.
4. Simplicity: Looking to make conference calls over landline phones? Be prepared to pay additional hardware and connectivity costs. However, this isn’t a problem with VoIP, which allows as many people to join a call that your internet bandwidth allows.
5. Customer service efficiency: From an operations perspective, you can use VoIP for more efficient customer service processes. Use call recording to train your team, and listen for frequently asked questions that can be used to inform your knowledge base.
6. Sales growth: VoIP can also be used for sales training, allowing sales managers to tailor their feedback in one-to-one meetings. With the right tools and leadership, you can grow faster.

For established organizations, making the shift to an internet-based telephony platform can seem costly. But the long-term gains go beyond savings. Implementing a VoIP system can improve efficiency, and empower teams to do their best work.

2. On-Premise vs. Hosted VoIP Services

With an understanding of the benefits, the next step is to implement a VoIP system. Typically, there are two approaches: On-premises and hosted (cloud-based).
Both operate what’s known as a Private Branch Exchange (or PBX for short). Each type of phone system has pros and cons depending on your business needs.
With on-premises PBX, all the equipment and hardware necessary for making VoIP calls are held in the office. Typically, this will be stored in your designated server room (if you have one). Calls are made from IP phones that connect to a PBX (or IP-PBX server) using a LAN connection.
Hosted PBX, on the other hand, is where a third-party company (like Nextiva) is responsible for handling the hardware, set up and maintenance of the PBX system. The headaches usually associated with getting started are no longer your problem.
Let’s check out the pros and cons of each system in more depth:

On-premises PBX Pros & Cons

Hosted PBX Pros & Cons:

If you choose the hosted route, be sure to find a provider that has skin in the game. In other words, a brand that prides themselves on building a high-quality product that they’re constantly iterating and improving upon.

3. VoIP Terminology

We’ve covered a lot of the VoIP basics, how it works and the technology behind it. Now, let’s check out some common terms used and what they mean.
These definitions will further help you to understand how VoIP works as you begin researching and implementing the right system for your organization.

Session Initiation Protocol (SIP)

SIP is a protocol used to initiate VoIP sessions in real-time. It also allows you to maintain, modify and terminate each connection.

As a signaling protocol, it is used when two or more endpoints communicate with each other via voice, video or messaging.

Public switched telephone network (PSTN)

PSTN is a worldwide collection of telephones and other voice-focused devices. This includes devices operated on a national or local level.

In simple terms, it’s the infrastructure that allows for private and public telecommunication. It interconnects telephone lines, cellular networks, fiber-optic cables, and undersea telephone cables, which allow devices to connect with each other.

SIP Trunking

Communications providers use SIP Trunking to connect PBX together with the traditional phone network to send and receive calls over the internet. It’s the best way to retrofit an existing office PBX with VoIP connectivity.

Codec

When talking about codec in the context of VoIP, their job is to compress VoIP data to save bandwidth and improve connection speed.

Some codecs also provide “silence suppression,” which stops data from being transmitted when one (or several) parties are not talking into their device. Codecs offer more than bandwidth optimization, they make your calls sound superior with twice the frequency range of a typical phone call by using the G.722 or G.729 codecs.

Dynamic Host Configuration Protocol (DHCP)

DHCP is used by client-side network devices to be assigned an IP address and other important parameters to make a connection. It also ensures IP addresses are unique. VoIP phones can be configured with a static or a dynamic IP.

Jitter

Jitter is the variation between the time it takes for a packet of data to reach the destination. When the jitter is high, users perceive this as “lag.”

Latency

Latency is the interval between a signal being sent and it arriving at the other endpoint. In other words, it’s the amount of time it takes for a user’s voice to be heard by the recipient.

How to Build a VoIP Infrastructure

As an IT leader, you may be considering the in-house route. Many find the level of control it offers appealing.
Before we dig into evaluating hosted options, let’s first look into what it takes to build an in-house VoIP infrastructure, so you can decide which system is right for yourself.

Step 1: Understanding your business’ requirements

As VoIP operates over the internet, you must ensure you have a strong and reliable connection. Part of understanding this is to figure out how many users you’ll need.
Pro tip: Start by assessing how many users you need in the short term and long term. For example, if you have 100 employees but expect employee count to grow by 50% every year, account for this growth ahead of time.
You’ll also need to define which shared resources are needed across the company. For example, three meeting rooms means three conference phones.
Once you know how many users you must accommodate, you can evaluate whether or not your current internet capabilities are sufficient enough.
Of course, even if you have 100 employees, not all of them will be using the VoIP system at the same time. But you’ll need to account for unexpected volume increases.
Speak to your ISP about your requirements and see what they can offer you. We’ve also created a VoIP speed test tool so you can see how much data your existing connection can handle:
Now, you can calculate the number of lines you’ll need to support business needs. To get an accurate number, consider the following:

• Phones: How many phones will you need over the next six, 12 or even 24 months?
• Numbers: If you have more than one physical location, you may need a separate business number for each
• Simultaneous calls: An inbound or outbound call is considered a line in use. If you anticipate a certain number of inbound and outbound calls at any one time (e.g. 50), then that’s the number of lines you’ll need

Step 2: Setting up the hardware

When setting up your VoIP system, you’ll need the right hardware to meet your needs. Here’s what a PBX system might look like:

 
Let’s break down the important elements laid out in the diagram above.

• Internet: You’ll need a stable internet connection to handle the number of lines you’ll need. Again, speak to your ISP if you need advice or to evaluate your needs
• Router & server: As VoIP connects to the internet, you’ll need a router that connects to your server. Each IP phone will then connect directly to the server
• SIP trunk: This connects to your VoIP service provider. This avoids sharing the same internet connection the rest of the business uses
• Wireless routers: Allows mobile devices using VoIP software/apps to connect to the system
• IP phones: Plug directly into the server via RJ11 connectors, allowing employees to make calls

SIP trunking allows voice data to travel over a dedicated line. This means that voice data has a dedicated line, which saves bandwidth from being eaten up over your main network.

Step 3: Choosing providers and features

There are dozens of providers available to handle your VoIP and PBX needs, all with varying costs and features.
We’ll cover how to evaluate different vendors in the next section. For now, let’s look into which features you should consider when building your VoIP infrastructure.
Here are five of the most critical (and common) VoIP features most businesses and IT professionals consider a “must-have:”

1. Voicemail (and call forwarding): There will be times where employees cannot answer the phone. Voicemail is critical for allowing customers and suppliers to leave messages.
2. Call recording: This is critical for industries that are heavily regulated. It can also be used as a strategic tool to improve your customer journey and train sales reps on their sticking points.
3. Auto-attendant: This feature “welcomes” callers with an automated message, and routes them depending on why they’re calling. For example, “press one to speak with customer service.”
4. Do not disturb: Allows users to block other incoming calls when they’re already on the phone with someone. Ideal for consultants who work directly with clients who wish to give their undivided attention.
5. Conferencing: Look for software with robust conferencing features, such as the ability to transfer files and make video calls.

With a list of important features, look for vendors who can support your needs. Some solutions only offer the basics (such as call management), while others come with advanced features.
A good on-premises phone provider will also assist with getting everything set up and offer long-term support. For example, many will help you with the following:

• Connecting your PBX to your ISP (via your router)
• Visit your office to install hardware, phones and confirm that everything works
• Configure vendor-specific services and settings

Have a list of questions when contacting vendors. Ask them how much support they offer during the setup process, and whether or not they send an engineer to consult and configure the VoIP system. We’ll cover more about the vendor evaluation process shortly.

Evaluating Cloud-Based VoIP Vendors

An on-premises system can seem appealing for flexibility. For many business owners and IT professionals, the amount of work can be daunting.
For most business leaders, they don’t want to deal with the intricacies of managing a phone system. Instead, they focus on developing products, acquiring customers, and offering excellent customer service.
Streamlining adoption, and making it as simple as possible, is the most appealing route when implementing any new technology.
Which is why hosted (or cloud-based) VoIP is usually the most attractive option. Instead of having to install everything manually, all you need is an internet connection, a headset, and a microphone.
Other benefits of switching to a cloud phone system include:

• Cost savings: According to Sage Research, businesses save an average of $1,727 per month when using hosted VoIP.
• Cheap international calls: Call anywhere around the world for as low as from as little as a penny per minute.
• Integrations: Most hosted solutions will integrate with your CRM, email marketing, e-commerce, and other platforms.
• True mobility: Make calls from the same number on any device, anywhere in the world. That includes smartphones and tablets.
• Unified communications: All channels are integrated into a single dashboard, allowing employees to view communications across the organization in a single feed.

Be sure to check out our comprehensive guide to selecting a VoIP phone system—it’s loaded with strategies, examples, and best practices. For now, let’s look into how to evaluate vendors and find one that’s right for you.

1. Define your requirements

Just like figuring out your requirements, it’s best to start with your business objectives first and reverse-engineer necessary features from there.
What do you want to achieve with VoIP? Is it to improve sales efficiency, customer satisfaction or reach business-critical goals?
Work with the boardroom and other senior decision-makers in your organization to come up with a requirements document. This should then form a mission for your implementation project, for example:
“The new VoIP platform for Company X must help sales reps close more deals, give support teams resources to delight more customers and make collaboration across the organization more efficient.”
With your mission defined, include features you need to achieve the desired outcome. For example, you might expect your hosted VoIP platform to provide the following:

• Direct messaging across teams
• Communications analytics and reporting
• Mobile apps to access VoIP anywhere, anytime
• Call recording
• Video conferencing
• Integrates with existing business processes
• Operates across different channels (email, phone, chat, text, etc.)

If you’re already using a VoIP platform and looking to switch, you should also ask potential vendors if they’ll help with migration, onboarding, and training.
In short, your requirements document should outline exactly what you need in order to achieve your business goals while making the setup and onboarding process as smooth as possible.

2. What’s your budget?

With all your needs fleshed out, you’ll need to know how much it will cost.
Some vendors will include all features in a single package, with a flat fee depending on the number of users needed. Others may charge extra for premium features. Bear this in mind, and be sure to check out the pricing pages of each vendor where available.
If you want to get truly granular with your budget, you can calculate the following:

• Total number of users required
• The average number of calls made each day
• The average duration of calls (segmented by team and organization as a whole)
• Hardware needed (e.g. desk phones, microphones, and headsets)

If you don’t already collect this data, then make a rough estimate by speaking to leaders of the departments that make phone calls as part of their day-to-day roles.

3. Shortlist and evaluate vendors

If you’re not familiar with the VoIP landscape, start by looking at popular software directories like G2. These can help you compare features across popular solutions, as well as reviews from existing customers.
You can also ask for referrals from your existing network. Sometimes, a quick post on LinkedIn is all you need for reliable recommendations.
Once you’ve listed your options, go through the sales process for each of them. State your requirements early, with a strong emphasis on your goals and desired features.
Ideally, sales reps will offer a demo running through the features that are most relevant to you and your goals. You’ll also receive sales material to share with other stakeholders involved in the process.
If you’re happy with a particular vendor, explain how quickly you’d like to get the system implemented. It’s also the perfect time to negotiate on pricing.

VoIP Security

Any IT professional worth their salt would be concerned about VoIP security. “How secure is VoIP?” is a common question we hear in the space.
The answer depends on your chosen approach. For example, if you’ve decided to build an on-premise system, then you’ll need to install and monitor the proper provisions against malicious attacks.
To improve your on-site security, make sure you have a firewall installed protecting the organization. Your router should also come with built-in security settings but speak to the manufacturer if you’re not sure.
If you’re worried that VoIP calls can be hacked, intercepted and spied on, fear not –  professionally installed VoIP networks are very secure. Your VoIP provider may offer encryption for your deployed phones. Since this varies by device and configuration, you will want to contact them to verify compatibility.
For peace of mind, ask VoIP providers the following questions:

• What accreditations do they have?
• What third-party tools or software do they use?
• How do they detect and prevent security threats?
• How well are employees trained on security protocols?
