If a call is made to a softphone line, the second call to this line (call to "busy") does not generate a journal entry in the ProCall client.


In most cases, the second call is not signaled in the estos SIP gateway because it is intercepted by the telephone system.


Enable the UCServer debug logs and start the Wireshark trace on the UCServer host.

Recreate the behavior.

Check UCServer logs (sipav_x.txt) or Wireshark intercept as to whether the second call was signaled in the UCServer SIP gateway.

Is the second call signaled in the SIP gateway?

NOCheck the PBX configuration.
YESContact estos product support and provide UCServer debug logs and PCAP recording.
