Re: Any comparison Study on MGCP vs H.323, MGCP vs SIP

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.

Thanks
