Re: UCM 6.1 Conference calls and placing on hold disconnecting

That brings up another interesting thing. Before you do the upgrade check
the version of firmware that your DSP's are running. Then check afterwards.
I recently had a GW that was giving weird issues with not passing DTMF (
intermittently). We noticed it when a user would try and "0" out of a UCCx
queue and could not.

It ended up being that we had 1 DSP that was on a different firmware than
the rest ( much older version ) and when one of those DSP's was hit the
problem was there.

We upgraded to the version you are recommending above 12-4-20.T2 and it
upgraded ALL of the DSP's to the same version and problem gone.
