SIP Trunks for Business from Planet Numbers
With BT about to ditch its PSTN and ISDN networks in favour of its new, internet-based IP system, you need to make sure your company’s ready.
Move to the cloud but keep your PBX
PBX stands for private branch exchange. It’s the typical company switchboard system that connects your internal phones to your external lines and allows internal calls within individual offices.
Many companies are ditching their PBX system to move to full internet-based VoIP when it’s time for an upgrade. But SIP (Session Initiation Protocol) is an alternative that gives you all cost and flexibility benefits of internet-based calls, but allows you to keep your current PBX system and traditional handsets.
