Can't make outbound calls, though not related directly to OpenSER.. Maybe someone here knows how to configure these guys. I have inbound calls being automatically dialed into a * extension but If I make any outbound calls I get a syslog output: 16:45:21.609 : 192.168.1.211 : WARNING : ( lgr_call)(458 ) !! [ERROR] Call::GetEndPoint- Can't find endpoint for phone number xxxxxx2018 16:45:21.593 : 192.168.1.211 : WARNING : ( lgr_psbrdif)(457 ) !!

Also, caller ID doesn't work - only shows the caller ID of whatever is set at the endpoint phone number settings and not what is actually coming on the line :( Nick
