We have a comprehensice call model with ICM, CVP and 2 gateways.
I want to transfer incoming call to PSTN using the 'Label' node in ICM script. The transfer is successfull and the callee answers the call and communicates with the caller. The problem is after exactly 5 minutes the call is disconnected and I can see the following message in the egress gateway :
*Sep 13 14:53:36.764: ISDN Se3/0:15 Q931: TX -> DISCONNECT pd = 8 callref = 0x00CA
Cause i = 0x80A6 - Network out of order
What can be the reason for the disconnect?
Is there any timer configurable on CVP or on the gateway that disconnects the call after 5 minutes?
