Benefits of VoIP PBX
A VoIP PBX is different than a traditional PBX in the sense that your telephone calls are transmitted via your IP network, hence the name IP PBX (or VoIP PBX). An IP PBX doesn’t mean you have to give up your existing analog lines either; there is a difference between doing VoIP on the WAN and VoIP on the LAN.
A lot of customers using an IP PBX continue to use their existing analog phone lines and integrate them into their LAN through the use of a VoIP gateway or a PCI card.
The two primary reasons to switch to a VoIP PBX are cost and flexibility.
