[Asterisk-Users] Just getting started with Asterisk

[Jesper Dalberg]

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 at 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...

I have no clue as to what might be the problem. Can anyone help a poor
newbie?
