Re: H.323 vs MGCP

Apples and oranges - H323 is a peer to peer protocol where MGCP is controller/controlee. There are ways to have multiple controllers with MGCP and survivable calls - like when ccm fails over or BTS. There is a way to do survivable telephony with H323 using AnnexE, this is supported on the BTS, unsure about CCM.
