SIP Trunking, or Session Initiation Protocol, involves combining voice and data information into one single connection. Using your current internet connection and an on premise PBX, a SIP Trunk can transfer the voice data over the internet, rather than using a traditional phone line. The savings come from dropping your existing phone provider in exchange for one consolidated phone and internet system.
