Yes, by connect, I meant how to co-relate the two calls. When I make calls from the application, the first call has an id which is stored by the application. I then do a consultation call, and at that point I receive the OCI.UCID of the first call as well as the id of the second call. So, I can relate the two calls.
But from the Avaya phone itself, there is no option to do a consultation call, so the second call does not have the OCI.UCID of the first call in the events.
Regarding your question - "You have a station that is the calling party for both calls, and has one on hold and one active."
It is a bit difficult to correlate calls based on the held calls as there might be more than one held call on the device.
