Forwarding external calls to external Number

[Kan Aky]

When dials by internal digits (1234), it's ok to forwarding. But when dial external digits (123456789) it's always busy. I explored similar issue, but not able to fix. CM was forwarding external calls correctly a while ago.

Do calls make it to the GW?

If so, what does the debug say about the disconnect?

What troubleshooting have you done, and what configurations have you reviewed?

[Kan Aky]

Yes,all calls to gateway. I don't how i see the debug of call.  

There was no change on Call Manager configuration, only some phone registration.
