On a CICS 6.1 system, when a conference call is created by users calling into the system thru a CP100 AA and upon completion, the Release key is pressed, the display shows "Call Transferred" and the lines are now kept connected thru the KSU until power is cycled or the bridge clips are pulled. This does not occur when the conference call is originated from within the system. Any ideas?

This one doesn't quite make sense to me. How are you creating a conference call through the voicemail?

The call comes into the system via the auto attendant. The caller enters the extension number and is routed to it. A second call comes into the system thru the auto attendant and again is routed to the extension (multiple intercom paths).

So the user uses the Conf. button to join the two calls? What model of phone is it? If they have softkeys the options of dealing with the call will come up. The other solution would be to hang up on the calls one at a time. I assume you've already checked to make sure the lines have disconnect supervision turned on. You could also try reducing the disconnect supervision time - I think the default is 400 msecs.

The model phone is a M7208. It is successful when the calls are separated and disconnected individually. 'Feature 3' is being used to create the conference. As for disconnect supervision, the provider says it is active. The key here is that if the call is originated from inside, it works corrected but when created from outside calls, instead of disconnect "Call Transferred" is displayed on the display. The possibility that a removal from the conference has happened at which time disconnect supervision may come into play at this point. The carrier involved is not well known to very helpful.

As Toner said, have you checked to make sure the lines are set for Supervised in the CICS programming?

Yes, I verified that the lings are set for supervision. I was finally able to perform a conference call through my CICS at home and reproduced the same thing with the exception that after 10-15 secs the lines disconnected. The phone service providers are different and so I am now sure of my first thought that the customer's phone provider does not have disconnect supervision active. I thank you for your responses to this. Hopefully someone else may also benefit from this in the future.

You may also have problems if the outside calls are from cell phone, as most cell providers do not provide a disconnect signal. Or at least verizon doesn't.

I hope you already solved this problem. IF not here is my advice. The reason you are getting calls transfered on the screen is because the call is technically transfered from your Voicemail system hence they are truely not conference calls but Transfered calls. That is why they are not disconecting because the lines are being answered by a person on the other end or the system thinks it has been. You can test this by reducing your Transfer call back under system programing. If the call is not answered it should return to Voice mail once it does hang up manually and this should disconnect the lines. It this does not work their may be a patch available for this problem on the Nortel Web Page.
