What is SIP Trunking?

Our SIP Trunking services deliver powerful new functionality to your new or existing premise-based phone system. SIP Trunks also help to reduce your phone and Internet costs, by consolidating them into one plan with competitive rates. And because lines can be easily added and removed as your business needs fluctuate, SIP Trunks create a more flexible and cost effective solution.

SIP stands for Session Initiation Protocol. SIP Trunk Lines represent the number of simultaneous calls to the public telephone network that can be made at the same time. SIP Trunk Lines are the virtual equivalent of lines coming in from the phone company or channels on a T1 circuit. SIP Trunk Lines can be oversubscribed by a maximum of 5:1 (Extensions to SIP Trunk Lines ratio).
