Voice Over IP is has been around for a long time; however, not until internet speeds were they really a viable option for businesses. We have worked with several companies now and this is one thing we find import to consider and that is “who is your ISP?”
One of customers is with Comcast as the ISP and wants to move over to Verizon to gain the advantages of inexpensive Fiber Optic lines now available at their place of business. The issue is they have Comcast VOIP and they would have to spend a lot of time swapping over their phone system.
We would suggest you look at third-party options such a Nextiva. This will allow you the flexibility of moving between different ISPs without a lot of configuration changes.
