I have recently updated our lab UC520 to the newest 8.1 package. Fortunatly I did this to our lab unit and not the clients unit. I beleive I have found a bug but I am not sure. The lab unit did not have Meet-Me configured. So I used the CME 4.1 Hardware conferencing guide, tried and true. Until 15.x apparently. I am unable to define my codec in the dspfarm profile section. See below for the output.
UC520(config)#dspfarm profile 1 conf
UC520(config)#dspfarm profile 1 conference
associate Associations this profile
codec The codec rate to be attempted for SCCP controlled
conference-join Define the custom cptone for conference join
conference-leave Define the custom cptone for conference leave
description Description about this profile
exit Exit from DSPFARM Profile configuration mode
maximum Configure maximum limit
no Negate a command or set its defaults
shutdown Disable or enable this profile
% Unrecognized command
If anyone has a good configuration example of the Meet-Me in 15.x, I would appreciate it. Or if someone has an answer that is just as good.
