I know that CCM 3.3(x) doesn't support SIP natively; I'll have to wait
for CCM 4.0(x) for native SIP trunking.

For now, can I use an IOS gateway to translate between H323 and SIP? I'm
thinking CCM connects to an IOS H323 GW. The IOS H323 GW connects to a
SIP Gateway.

We are looking at connecting to another service provider that really
wants us to use SIP instead of H323 to connect to their gateways.

Cisco Gateways can act as SIP User Agents (endpoints, basically).

I don't know that they would be able to translate from an inbound SIP request to H323 well, as that would be a "Voip hairpin" - something the routers couldn't do until the very latest 12.3 code. I've never tried this code so I can't say it will work.

I'm assuming it'd look something like this:

Service Provider -> Network connection -> your gateway -> CallManager

In this case, with 12.3 code, you could make a VoIP Peer with a SIP session target, and an H323 Voip Peer with CallManager as the target. As I said, this is supposed to work in the very latest 12.3, I couldn't say if it does, or how well it might work (my 12.3 experiences have all been very bad so far).

Supposedly there is a new "SIP Proxy" software product that works with
CCM 4.0. Our Cisco AM could not describe it.

The Cisco SIP Proxy Server has been around for quite a while and info on it
