VoIP trunks from service providers use SIP for call control and routing Enables IP/SIP connection to carrier
IP networks. SIP sets up and tears down calls
call is routed via the carrier’s IP network
Calls are handed off to a PSTN gateway for the last mile if they are bound for E.164 numbers.
On-net calls remain native, “pure” IP
