Fast Busy Signal

when ever I try to dial out via my sip trunk, I get a fast busy signal. from the logs I see this error;

[Sep 18 14:18:31] NOTICE[29037]: chan_sip.c:18160 handle_request_invite: Call from ‘1002’ to extension ‘912128329127’ rejected because extension not found.

The SIP trace is irrelevant. In fact it doesn’t indicate any problem.

The context selected by sip.conf for calls from 1002 does not contain a dialplan rule that matches the pattern 912128329127. The CLI output just before the bit you included would probably have told you which context it thought 1002 was in.

david55 , below is the complete out put form the console. thanks for your help;
