The calls are dropped after 12 seconds with cause code 127 INTERWORK..

The calls are dropped after 12 seconds with cause code 127 INTERWORKINGUNSPECIFIED

Our CTI application is handling calls transferred to CTI route point, the call is answered, media connection is established and we use RTP stream to play a prerecorded message. When the message playback is finished, the call is put on hold and awaits for pickup by an agent.

The application is using JTAPI library and from occasionally calls are disconnected and we receive FAILED event. After enabling JTAPI logs, we can see that the call was answered, the SetRtpParams call was successful and the “StartReception” was received. After about 11-12 seconds we receive “StopTransmissionEvent” and at the same time call state changed with state DISCONNETED and cause code INTERWORKINGUNSPECIFIED, and JTAPI events ConnFailedEv and CallCtlConnFailedEv ciscoCause=127 (INTERWORKINGUNSPECIFIED).
