Call Join in CME

Unanswered Question
Oct 14th, 2008

When attempting to join two calls I get a message indicating Cannot Complete Conference. Attempts have been made to put this on the Hold softkeys and Active Call softkeys, both to no avail. Any thoughts?

I have this problem too.

How do you have your dsp's setup in your router? A dsp chip that is doing conferencing can do only that. So if the dsp is assigned to be an mtp for hold, it probably can't be reassigned on the fly to end the mtp and merge the two calls to a conference. What sort of dsps have you got? The key is to have more than one physical chip on the pvdm you have in the router. One pvdm can have multiple chips. One chip can't do conferencing and mtp.

Hope this helps

That makes sense, Rick. There are (2) 16 channel DSP's in the box, a single PRI and (4) FXO ports. So at this point, there's no hardware conference bridge built in the box, and I don't believe one can be either given the resources on the box.

I doubt that this is still a live post, but I came across it while trying to answer that question myself.

From https://supportforums.cisco.com/message/1139258 :

"Join—Joins an established call  to a conference. You must first press Select to  choose each connected call that you want to join in a conference, then  press Join to join the selected calls to the  conference."

In other words, you must hit the more soft key until it shows the "select" option, select the line you want to join then select the "join" soft key. If try to hit join before you hit select you get that error message.

Hope this helps someone.
