SIP/prov... is circuit-busy
-- SIP/prov... is circuit-busy == Everyone is busy/congested at this time (1:0/1/0)
Make sure:
- You are properly registered to the Provider
- You are sending correct Destination Number Format
- You are sending correct CallerID Number Format
- Using correct codecs
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 not 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.
