Improper call termination after GCEV_DISCONNECTED with active Web Service

[Maciej Zasadzki ADVICOS]

We encounter situations where, after a call disconnects, VoiceGuide does not properly terminate the session. In the attached example, during the processing of the Web Service target_user_data, a disconnect occurs (GCEV_DISCONNECTED), with the line in LS_WS_CALL state. Likely due to asynchronicity, upon receiving a 200 OK response, VoiceGuide continues executing the script flow instead of terminating. Consequently, the call remains active until the 20-minute timeout set in the transfer module. Only after that timeout does proper termination occur (GCEV_DROPCALL, GCEV_RELEASECALL, RecEnd).

How should we configure VoiceGuide so that after GCEV_DISCONNECTED, the Web Service callback does not continue the normal script flow but immediately ends the session? Attached is an anonymized log.

Please post the ktTel trace capturing these times.

Looks like something interrupted the stopping of the recording that was initiated here:

also, a quick fix would be to check that the value of the $RV[Conf_LineId_2] or other similar Result Variable, before getting the original line to just hold for 20 minute in the "Wait_till_end_of_call" module:

073718.004   20  17   5    83 state [Wait_till_end_of_call] Playing wav () | 
073718.007   20  17   5    83 t     timer set   10 sec : EV_TIMEOUT_HANGUP
073718.008   20  17   5    83 t     timer set   1200 sec : EV_TIMEOUT_GOTOMODULE

The attached trace doe snot show the Result Variable assignments, so looks like trace was captured at a lower log level.
