I have a CTI C# application that started randomly when attempting to transfer the call from within the CTI application received the following exception:
$[2020-02-19 13:05:20.947] <14924:DoTransferCall> Error in DoTransferCall method Unable to find the consult terminal connection for contact 37505057 on terminal 3241018<-tc->sip:3241018@ushcsip.com<-c->37388919.
at Nortel.CCT.ProxyLayer.SessionProxy.CallRemoteVoidMethod(ResourceProxy localResource, String methodName, Object[] args)
at Nortel.CCT.ProxyLayer.TermConnProxy.CompleteSupervisedTransfer(IContact consultContact)
at CCTCti.CTILite.DoTransferCall(Object transferredContact)


This error does not occur on every transfer. Any idea what could be causing this, could it be a network issue? I'm attaching a log from the agent it contains both a failed and successful transfer.

I'm going to say that's way too involved to get into properly on the forum (but, of course, other community members should feel free to do so, if they wish) ... for my part, I'd prefer you open a [technical ticket] with that one so it can go in my work queue, however, you'd likely need to upgrade your membership too.

Quickly, I would say it means that the original call leg was lost. Most likely, the customer hung-up before the transfer and the software continued to try complete the transfer anyway. Of course, I imagine you've considered this and thus, it would take a good amount of trawling through those logs to put together the IDs and make a more informed guess.
