Benefits of Switching to an Enterprise VoIP Phone System

Besides its advanced feature set, an enterprise VoIP system offers the following benefits that traditional landlines or PBX don’t:

  • Cost savings: VoIP calls are typically significantly cheaper than landline calls, especially long-distance and international calls at scale.
  • Scalability: VoIP systems can easily scale up or down as your business needs change. You can add or remove lines as needed without installing new hardware.
  • Mobility: Employees can make and receive calls from anywhere with an internet connection, including their smartphones and tablets – ideal for companies with remote workers or multiple locations.
  • Features: Enterprise VoIP systems offer advanced features — auto attendants, conference calls, call forwarding, and call recording — not available on traditional landlines or PBX.
  • Reliability: They’re more reliable and can be backed up by cloud-based services to ensure uptime.

Enterprise VoIP FAQs

This is a phone system that is operated and maintained by a phone service provider instead of on-premise hardware. Cloud PBX lets you lower costs, improve phone service uptime, and achieve greater business continuity.

The primary difference between enterprise and small business VoIP are the needs of the business. Enterprises stand to benefit from popular features such as call recording, voice analytics, call queues, and team collaboration.

It's easy to transfer phone numbers to Nextiva through a process known as porting. Porting lets you move your phone number to a new VoIP provider.

You can transfer any number you use, including:

Nextiva handles everything related to moving your phone numbers over. All you need to do is submit a letter of authorization online. Our porting team will advise you of the port-in date. From there, you can begin receiving calls through Nextiva's cloud phone system instantly.

Transferring business phone numbers will take approximately 2–4 weeks, depending on the previous carrier. In the meantime, you can use temporary numbers.

Watch this short video to see how to transfer your phone numbers to Nextiva:

video on how number porting actually works

Larger businesses need to identify a partner that can support their broader business needs and vision for growth.

Areas to focus on include service uptime, platform reliability, customer support availability, and the ability to ramp services up as your company grows.

Top features enjoyed by enterprise VoIP users include call pop, voicemail-to-email, call recording, auto attendant, conference calls, custom dashboards, and call logs.

Every phone line consumes about 100 kbps of bandwidth. For instance, 100 lines of active calls will require 10 Mbps of asynchronous network bandwidth.
