Hi list, I have been looking around for a while now, and cant seem to get to the bottom of my problem. My setup is that I have a separate SIP server that servers my SIP subscribers, and I want to use Asterisk purely for voicemail for now. So I set up a common SIP extension at my SIP server, and made Asterisk register it, so that normal users can forward calls to that common extension, and Asterisk can analyse B-numbers to figure out which mailbox to enter. That's the basic idea. I have never used Asterisk before, and have (well had) no clue where or how to start, so I started in sip.conf, and just wanted to get the demo first. So I registered as ... register => mygenericforwardextension:password@legacy.sipserver.com:5060/9999 .. and then set up the 9999 extension in extensions.conf as shown ... exten => 9999,1,Goto(default,s,1) When I place a call to "mygenericforwardextension", the SIP signalling (INVITE) comes through to Asterisk just fine, but at the end I get a busy tone, and asterisk (with debug switches) gives me... -- Executing Goto("SIP/-08363000", "default|s|1") in new stack -- Goto (default,s,1) -- Executing Wait("SIP/-08363000", "1") in new stack -- Executing Answer("SIP/-08363000", "") in new stack -- Executing DigitTimeout("SIP/-08363000", "5") in new stack -- Set Digit Timeout to 5 -- Executing ResponseTimeout("SIP/-08363000", "10") in new stack -- Set Response Timeout to 10 -- Executing BackGround("SIP/-08363000", "demo-congrats") in new stack -- Playing 'demo-congrats' (language 'en') Oct 5 09:58:17 WARNING[137733120]: file.c:537 ast_readaudio_callback: Failed to write frame -- Executing BackGround("SIP/-08363000", "demo-instruct") in new stack Oct 5 09:58:17 WARNING[137733120]: file.c:537 ast_readaudio_callback: Failed to write frame -- Playing 'demo-instruct' (language 'en') I have no clue as to what might be the problem. Can anyone help a poor newbie? Regards, Jesper Dalberg
