The SIP 503 error message is generated when the service you are trying to use is unavailable.

Please make sure all account details and the server hostname are entered correctly, if the issue is appearing randomly it may be temporary issue with your VoIP provider.

For additional assistance regarding this error message, please contact your VoIP service provider.
