I've got a customer (2 locations one X128 one E128)

I can't get the problem to duplicate when I'm on site however both sites complain of this problem.

Situation:

X 106's phone rings for an incoming call on line 1 (analog CO) He/She is on the phone, then another call comes in, they place line 1 on hold or transfer the call to another department. They go to answer line 2 and the call on line 2 (another analog CO) gets dropped.

My theory is they are hanging up on the caller on line 2 somehow, however I have watched them answer calls before, and they appear to do it properly.

This never happens when the second call comes over line "3" (Actually line 19, first line of the PRI channels)

Has anyone ever seen this problem. I cannot duplicate it for the life of me.

Part II of this question.

If I install TAPIT or another SMDR software, will this inform me if the call was answered then hung up on? I've never used the SMDR on an ESI system to date so I'm not familiar with it at all.
