We have applied the handler to some sites where calls were hanging due to network issues. The handler killed the hanging interactions only partly.
An ACD-call is always transferred to a user queue
and a station queue at the same time and then, when the call hangs, you can most probably kill the station queue call, but not the user queue call.
We always have to switch and restart the CIC still. Sorry to say that.
What we have done to improve the situation is to increase the TCP timeout from 3500 ms on the line to 10000 ms. Same applies to the SIP-Proxy, 10 seconds. Now we are on the safe side, but still I would be happy if such a tool would come up some time in the future.
