Hi All,

H.225.0 states that "one GRQ is sent per logical endpoint; thus an MCU or a Gateway might send many". Do I take it therefore, that a H.323-to-ISDN gateway with a maximum capacity of n lines must send n GRQ and RRQ messages; i.e., one for each line? If this is the case, can anyone shed any light on the reasoning behind it?

Also, can anyone explain the relevance of the endpointAlias field in the GRQ message and the terminalAlias fields in the RRQ and RCF messages to a H.323 gateway application? After all, a gateway is supposed to be transparent to normal endpoints and does not need to be directly addressed by them.

Thanks,

Mohamed
