Hi there, REALLY need some help on this one. I'm using an unsupported version of Call manager 18.104.22.168, along with attendant console. TAC is no help even with SmartNet because of the version I'm on. I've been having problems recently with calls that are transferred being dropped before they are answered by the person being transferred to. I'm attaching just a couple minutes worth of Call Manager and Attendant console logs where I know there was a failure. The Call is coming in Via the Attendant Console (pilot point 7600) and being answered by DN 7602, DN 7602 answers, speaks to the caller and transfers them in this case to the the Sales Group which is 7253. The caller calls back, says it rang a couple times and they were disconnected. Please any assistance would be extremely helpful. I'm not a Cisco engineer, just an IT guy with the responsibility, I can't tell heads or tales of the logs but a common theme I see is "CPIClass::createInstance(
), Caller's error,inappropriate InstanceIndex"
