Re: [Megaco] Uniqueness of context ID

Like to add:
there is a unique name space of ContextID values because there is a
single CA (H.248 Control Association) between a pair of MGC and MG
entities.
(Please note that there is not any difference between a physical or
virtual MG, - there's just one CA.)
