Avaya IP500v2 SCN channels question

[Tim-HMA]

Hello,

I'm currently running into a channel capacity issue on calls over an SCN and I think its because of licensing. Can someone help me understand what is going on? Here is the Scenario:

-IPO A and B are both IP500v2 on R9.

A uses B for centralized voicemail as well as meet me conference bridges exist on B.
A has 5 Voice Networking licenses, which amount to 20 instances. A also has 74 VCM channels.
B has 4 Voice Networking licenses, which amount to 16 instances. B also has 32 VCM channels.

A calls B on many channels for a conference bridge. During testing, I was able to tie up 31 channels to a single meet-me bridge on B before hitting my head (next call failed, "no available channels"). I have both sides of the trunk set to 128 inbound and outbound channels.

My questions:
How was I able to use 31 channels on A if I only have 20 voice networking instances?
What are the VCM licenses used for? I noticed congestion on B's VCM channels at the time I was testing.
What licenses do I need to increase the capacity between IPO's for more concurrent calls at a time?

Thanks

The reason is that your trunk channels are only used to start the conference and then the calls are in the local conference bridge. If it is programmed correctly
