Hi R,
The context of my question is VoATM rather the SVC setup procedures as described in RFC 3108, it describes two methods for bearer set up in ATM network using MEGACO, but I feel is that these terms are more generic and are not related to only MEGACO SDP, and i feel that these terms have been taken from the ISUP standards (at least thats what the 3G specs say) but my question is that why is the need for two different methods and under what scenarios do we use them.
