The Number you have Dialed is not in service on outbound calls,

Hi there i have a problem with making outbound calls, it just keeps saying the number is not in service all incoming calls work fine its just outbound i believe i have set up the trunk things correctly according to tut’s i have found how ever can seem to get this working

Check the /var/log/asterisk/full log for one of your calls and see what your upstream provider is telling you the problem is.

Have you setup OUbnound route to handle the number you wish to call?
