I am trying to find out if a CallManager 4.x system can communicate to an IP Telephony Service Provider over SIP to their Sessions Border Controller. From what it looks like, I will need an IP2IP gateway to talk H323 to the CCM and SIP to the ITSP. Has anyone successfully done this before?
Any help or experiences would be greatly appreciated.
I'm trying to setup the same thing and was wondering whether you managed to get this resolved in the end? I can successfully make outbound calls from CCM4.2(3) but I'm having some problems with the inbound. Any help appreciated.

I seen only 5ms between invite and busy. Not sure if the h.323 is being activated. Check it out with "debug cch323 all". May be CCM is rejecting the call for some reason, unfortunately I'm not good at CM enough to tell you why.
