4.6 SIP Trunk Configuration
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.
The SIP TRUNK MANAGEMENT page allows the administrator to configure SIP trunks used by
PLANET IP PBX. Select Trunk -> SIP Trunk, and one can add, edit, and delete SIP trunks. Go to
Service -> IP PBX Service, and click RELOAD to activate changes.
