I have scoured the internet to find documentation about reverse autopatch but have had no luck. I have been able to get autopatch working without a problem and have had _limited_ success in getting allstar(dial) to answer. I was able to get allstar to answer and allow me to run DTMF with the following, but really all that I want is reverse autopatch or both.... If I make any real changes to the stanza in extensions.conf I get an error like: Using INVITE request as basis request - 1939985154@198.199.84.66 Found no matching peer or user for '198.199.84.66:5060' [Mar 30 16:15:32] NOTICE[575]: chan_sip.c:14351 handle_request_invite: Failed to authenticate user "Caller ID Strings..." <sip.conf> [general] allowguest = no match_auth_username=yes register=REDACTED:XXXXXX@gvgw.simonics.com/2230 context = default allowoverlap = no ; Disable overlap dialing support.
