[a.burlaos]

Hi,

Does anyone encountered the same issue regarding the Hardware Conferencing using SIP IP Phones for CME?

Scenario:

1. Phone A calling Phone B

2. Phone A pressing Conference button and calling Phone C (Phone B is put on hold).

Phone A tried to merge the calls but it is not working.

Note:

1. Hardware Conference bridge status for SCCP is "UP"

2. Debug ephone hw-conference result

Awesome. Conferencing defaults to 8 participants per session. You will need to increase the maximum participants per session but that will lower the total number of conferencing sessions that you can have since more DSP resources will be utilized.

I’ve created 10 sessions for my conference bridge, I think that would be ok.

That would default to 8 participants only per session. Like I said, if you need more than 8 participants per conference session, you will need increase the maximum participants.

I already configured the maximum participants to 16

Ok. You should be good now. :)
