What Is an Enterprise VoIP System?

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.

How do I transfer my phone numbers to Nextiva?
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:
- Landline numbers
- Wireless/cell phone numbers
- Virtual numbers (Google Voice, TextNow, etc.)
- VoIP phone numbers
- Toll-free numbers
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.
