Hi,
There are studies on the comparision of the two competing protocol SIP and
H.323. However, MGCP can also provide call control functionalities. A
network with MGCP only (Call agent, MG etc) can provide basic VoIP service
too. Then my questions are
1. Are there any comparison study between MGC
Yes, I need this comparison too, please help.

For t
speaking of telephony/telecom protocols, are there any "voice subscriber"
MIBs/models - SNMP or CMIP oriented. I'm just looking for a model used
for voice subscribers who are provisioned w/ some combination of AAL2,
VOIP, GR-303, V.52.
