I haven't been successful in getting this to work. The issue looks to be that Asterisk is wanting peer authentication for the invite request as it sends back 401 Unauthorized. I am using FreePBX 2.7 and have tested both Asterisk 1.6.1.18 and 1.6.2.9. My trunk settings are
type=peer transport=tcp qualify=yes insecure=port,invite host=10.10.1.31 context=from-internal Here is snippets of the SIP debug output. I added in the debug "Peer has insecure flags" to see what was happening. INVITE sip:2...@voip.mydomain.net;user=phone SIP/2.0 FROM: ""<sip:2...@exch.testdev.local;user=phone>;epid=079E8F8013;tag=849256682 TO: <sip:2...@voip.mydomain.net;user=phone> ... Sending to 10.10.1.31 : 19219 (no NAT) Using INVITE request as basis request - 5c97e0f0-5456-4b82-a7f4-e7f2adeba338 Found peer '2001' for '2001' from 10.10.1.31:19219 Peer has insecure flags no SIP/2.0 401 Unauthorized Due to Exchange making the call from / to the same valid extension Asterisk is wanting authentication for the 2001. I thought by using host and insecure in the trunk settings if the from address matched the host it would use that as the peer. Alternatively I couldn't find the option to tell Exchange to make the call from a different extension. In looking at an anonymous call Asterisk doesn't have a peer for the from number so it looks in from-sip-external. INVITE sip:1112223...@voip.mydomain.net SIP/2.0 From: "1112223333" <sip:1112223...@voip.remotedomain.com>;tag=as1c8404f3 To: <sip:2223334...@voip.mydomain.net> ...
