Incorrect number format

If Provider returns something like:

-- Got SIP response 503 "Service Unavailable" back from xxx.xxx.xxx.xxx

Try to add '00' (if Provider is in Europe) or '001' (if Provider is in USA) to Provider Rules to destination.

Some Providers wants numbers with international prefixes.



Codec mismatch

Check codecs for your server and your provider. Often there are no matching and call is not possible.



Provider has no available lines to service the call

503 "Service unavailable: no more gws" back from xxx.xxx.xxx.xxx - Provider does not have more open lines to serve your calls.
