Our environment is a register free setup, and our phones are set as host=dynamic. The problem we are experiencing is for inbound calls:
Name/username Host Dyn Forcerport ACL Port Status Realtime
222/222 (Unspecified) D N A 0
Unmonitored Cached RT
So when we DIAL 222 we get:
WARNING: app_dial.c:2198 dial_exec_full: Unable to create channel of type ‘SIP’ (cause 20 – Unknown)
My question is how can we get Asterisk to fill in the gaps (ie, ipaddr, port) for a dynamic peer in a register free environment.
