About CallCtlTermConnHeldEv when hold call is retrieved

HD_RR401 · ‎03-14-2021

Hi,

We use sandbox (CUCM12.5) to monitor call events between extension terminals (using JTAPI).
When we executed the hold on one extension, CallCtlTermConnHeldEv was generated, and after waiting for about 20 seconds, when the hold was released, it returned to the call state and CallCtlTermConnTalkingEv was generated. But almost at the same time, CallCtlTermConnHeldEv and CallCtlTermConnTalkingEv occurred.

The timeline of the event is as follows.
[2021/03/13 20: 21: 58.143] [CallCtlTermConnHeldEv]
[2021/03/13 20: 22: 15.087] [CallCtlTermConnTalkingEv]
[2021/03/13 20: 22: 15.191] [CallCtlTermConnHeldEv]
[2021/03/13 20: 22: 15.883] [CallCtlTermConnTalkingEv]

It looks like CallCtlTermConnHeldEv and CallCtlTermConnTalkingEv are occurring twice in one hold.
Is this behavior a CUCM specification?

Thanks.

I don't think I'm seeing that on my 12.5 system (using IPC and a 7975) (see attached).

Via modifying the makeCall sample (note, observing only the near-side address and terminal:)

12:12:46.27 Holding call: (P1-dstaudt) GCID=(1,3009)->ACTIVE

Are the events from different terminal connections? You should get a set for each one in the call if you're observing both ends...

Possibly two (identical/redundant) observers are in place?

If you need a detailed analysis, I would suggest opening a ticket with DevNet Developer Support, who can take a look at the detailed logs to see what is happening: https://developer.cisco.com/site/support/
