[cisco-voip] H323 Gateway needed for SNR mid-call features?

[Nick Matthews]

Digital voice is basically PRI channels.  Ex: the 2901 can fit 3-256
PVDM but doesn't have the horsepower to manage that many channels, so
it has a 100 digital voice channel capacity.

The metric you're going to be more interested in is VXML capacity.
It's pretty close to the CUBE and MTP numbers if you have those.  They
aren't published since they're benchmarks and not promises.  You can
contact your account team to get more details if you're not already
privy to that information.
