2.6. Trunk
A SIP trunk refers to a SIP account on a remote call routing or gateway device. A
practical example is an account at an Internet Telephony Service Provider (ITSP)
where a call is routed to a SIP client or off-ramped to an analog subscriber via PSTN.
One could also build SIP trunk to a remote IP PBX to reach its extensions and PSTN
ports.
