Introduction
When all resources on the telephony server, eg. sip-licenses are in use and another call comes into the system, the call cannot be accepted and is therefore rejected.
General Information
The default sip response for this use-case is Cause 16, but Cause 17 can be configured if required.
See also SIP Responses / ISDN Cause Codes
The setting can only be configured if you have access to the jtel telephony server. It can be found here:
