When executing: Dial (SIP/##########@###.###.###.###,60) I get about 15 seconds of ringing, the called party rings, but if not answered in the ~15 seconds I get back SIP 480 temporarily unavailable. If the call is answered everything is fine and the call will continue as expected. The call is being passed to a TNT media gateway then to the PSTN via a PRI The TNT reports Q850 cause 19 and responds with SIP 480 Somehow the TNT thinks the called stopped progressing on the PRI after 15 to 20 seconds. The Telco says they have done a capture and are getting a normal release, in other words their switch is not terminating the call or sending any Q850 message. I can not find any timers in the TNT that might cause this, and it is not reporting any expired timers. Any ideas? Does the SIP INVITE from * to the TNT contain a timeout? If so is it possible the, 60 in the dial command is being ignored? Either; The TNT got a maximum time parameter from asterisk and it has been exceeded, so the TNT responds 480, or; The TNT has a timer that expires after n seconds and sends the 480 on its own, or; The Telco is not seeing the progress they want to see and is sending the Q850 cause 19. Any opinions, suggestions? -------------- next part -------------- An HTML attachment was scrubbed...
