unexpected "hang up" Calls

does anybody know about a problem between Tserver for Definity 6.5 and Avaya switch. since we migrated from Version 5.1 to 6.5 we have a lot of (500 per day) unexpected hang up Calls. that means: the agent answers the call and 3 seconds later the call is disconnected.

and it’s definitely not the customer who hangs up.

We had this problem. I think yours also could be same if I am correct… Check your tserver log file for EventLinkDisconnected. If you found then there must be disconnect between PBX and Tserver. ",2002719 12:48:30,10180,594

I am sorry, it must be something else… check with Genesys Tech Support for help.

Is this for outbound calling or inbound? I have seen this with outbound where the wrong call is being disconnected on the transfer o the agent.
