TMS and Conductor Dial Out Conference Empty Source field

[fedor.solovev]

Hi, dear support community.

Can someone help to clarify this, please:

TMS 15.5 plans a conference based on Conductor XC4.3.1, which is connected to CUCM 11.x via SIP trunk.

Conference starts fine; however, if add a cell phone to dial out, Conductor sends SIP whiteout Source field. It is only an IP there.

Conductor doesn't pass a conference number.

Is this only seen on one particular device or several, and which ones?

What conference bridge is being used with Conductor?

Is the display name blank, the source address, or both?

Hi, guys. Thank you for answers.

It is seen both at CUCM site and at Conductor call logs since in INVITE the From field shows a name of a conference instead of Calling Number. This name is successfully shown at a jabber window if add it to a conference. However, CUCM receives no Calling Number, passes it to GW and GW drops the call.

(Yes, it is easily to correct by configuring translation rule, but I wish Conductor sends appropriate INVITE).  TPS 4.4 is used as a conference bridge with Conductor.

Unfortunately, this is expected behavior.  When Conductor dials out, it doesn't use a valid source SIP URI or meeting ID, unlike MCU or stand alone TP Server.  Because of this, Conductor works much better with dial in and/or One Button to Push, as opposed to Automatic Connect.
