UC520 not allowing another call to conference call
UC520 is not letting another caller to be added to an existing conference call, when I try to add another person and hit conference it disconnects one of the callers from ongoing conference call. I have a 64 channel DSP installed.

Don't forget that each DSP is related to a Conf profile as shown below. Your profile must be set up in mixed mode. Your original question referenced the number of participants not the number of sessions:)

Each DSP can support a maximum of 16 G.711/G.729A/G.729 participants (mixed-mode), so this translates to:
