Originate problem ( hangup )

Hi. I am using Asterisk 1.2.7 and are trying to get originate (in Asterisk API) to work. It worked flawlessly on my old Asterisk@Home, but now I get some strange problems.

When I initiate the originate-action, Asterisk calls my Ip-phone, but when I answer, it just hangs up again (without ever reaching through to the Exten).

This is my Originate:

Action: Originate Channel:SIP/63 <-- My sip-account Context: internt Exten: 92626446 <-- Number i want to call Priority: 1 Callerid: 63000063

Here is the response from the API (telnet)

[code]Response: Success

And here is the log from asterisk:

> Channel SIP/63-e3e2 was answered. == Starting SIP/63-e3e2 at internt,92626446,1 failed so falling back to exten 's' == Starting SIP/63-e3e2 at internt,s,1 still failed so falling back to context 'default' Jun 28 00:03:27 WARNING[21357]: pbx.c:2353 __ast_pbx_run: Channel 'SIP/63-e3e2' sent into invalid extension 's' in context 'default', but no invalid handler

And here is my channel in sip.conf

[63] type=friend username=63 secret=XXXXX host=dynamic disallow=all allow=ulaw allow=alaw allow=gsm context=internt

And finally (puh), here is my extension:

[internt] exten => _63,1,Dial(SIP/${EXTEN}) exten => _XXXX./63,1,Dial(SIP/${EXTEN}@ip24_63000063)

I would be very grateful for any help. Been trying to deal with this problem for hours…

Your extensions.conf doesnt include an extension for 92626446 in the context internt - just what Asterisk says on the CLI.
