MC/MCU related

[Sunil Chandra]

Hi Chris,

      I have following queries related to MC and MCU.

      1. In H.323 section 6.2.8.4, there is a table which gives the terminal
      types values for various terminal types. In this table there are certain
      entries marked as NA. Does this mean that these terminal types are not
      possible? for example, an MCU is not possible without an MC.

      2. Why a terminal can not have a data MP?

      3. Why there is no clause for an entity containing MC with audio MP only?

      4. Is it always necessary to have an MC in Gatekeeper?

      5. If a call signalling is routed through Gatekeeper, and there exists an
      MCU which is not involved in this call. Is it possible for the Gatekeeper
      to involve this MCU to create an ad-hoc conference from this call. If yes,
      what is the procedure? If not, why?
