this may or may not be appropriate discussion for this list but i guess it concerns the future of SIP in India.

briefly, the indian government is considering opening up and deregulating internet telephony (which has so far been illegal in india). the TRAI (Telecom Regulatory Authority of India) is the indian equivalent of the FCC. amazingly, their consultation paper only mentioned H.323 and not SIP. i intend to be present in their open house session next week. there are a couple of things that their paper (available at www.trai.gov.in) raises. i would invite the list to point me in the correct direction.

1. QoS: as a regulator, TRAI (and also regulators in many other countries) may want to lay down the QoS for service providers (where the competition is restricted). what is the SIP support for QoS?

2. While SIP is already burnt-in into many products, what are the specific issues still open in the SIP definition that disqualify it from being carrier class (if any)? what is the timeline to get a freeze on these issues?

3. are there any cost advantages inherent in the SIP protocol as opposed to H.323? (I mean, are there any patent, code complexity and hardware issues that may contribute to greater or lesser cost of deployment)?

it would be nice to have the list's views that i can present to TRAI on the 28th december (there goes my vacation!).
