Techopedia explains Session Initiation Protocol Trunking (SIP Trunking)
Using the Session Initiation Protocol, SIP trunking basically controls the routing of telephony signals within the network. This method may require a certain amount of available bandwidth and features like firewalls. Engineers may also have to look at challenges like latency, packet loss, or delays in packet delivery. In general, Session Initiation Protocol trunking can save companies money by promoting more efficient VoIP connections and eliminating the need for some kinds of analog public switched telephone network (PSTN) connections.
