SIP Trunking

With SIP (Session Initiation Protocol) Trunking, your PBX is connected to the public switched telephone network (PTSN). Service providers distribute traffic among multiple carriers, so they can offer the best rate for any given instance of voice data transmission. SIP Tunking is a popular choice because it is so cost effective- calls can be carried to end users using the least expensive and most efficient routing mechanism available at the time the call is placed.

SIP Trunking allows a business to use an internet connection for all multimedia information transfers, and can also be more flexible than some other VoIP service offerings.
