Can you have a primary Meetingplace IP/GW talking with one audio server, and have another IP/GW talking to another audio server, and cascade audio conferences through between the two audio servers?
The maximum number of simultaneous meetings equals the number of ports divided by two. The servers support up to 550 sessions (participants) per meeting. However, you can cascade up to three Audio Servers to achieve a total of 1650 audio sessions in a single meeting
