I'm confident the answer is yes, but I'd like confirmation:
Can a 3515 MCU be configured to support SCCP ad-hoc/meetme conferencing at the same time as H.323 dial-in conferencing?
Do resources need to be allocated to one or the other, or are they pooled, and available first-come, first-served?
The IP/VC 3515 MCU can support both SCCP adhoc & H.323 dial-in conferencing. The resources, however, cannot be pooled. They need to be specifically allocated to each protocol in groups of 6.
Therefore, if you have the 3515-12 you can basically have a 50/50 allocation of SCCP to H.323. The 3515-24 with 24 ports gives you a little more flexibility.
