I had a weird question about the SIP adhoc conference with the ccm 5. Here is the scenario:
- I start a SIP adhoc conference with a 7961GGE. I call many types of phone (7940, 7970, gsm). I can't add more than 6 participants.
I thought that this limitation was due to the fact that the initiator makes the audio mixing. But in fact I can see on wireshark that all the RTP stream go to the PBX.
Moreover, if I unplug the 7961, the other participants are still on the conference.
It means that the PBX is doing the audio mixing right ? How to be sure about that ?
Therefore, why is there a limitation on the phone ?
