Hi there,
We have a realy big issue to route a call via our CCM Version 5.0 -- SIP ---> 3845 -- H323 ---> H323 Gateway (International Service Provider).
We're using CCM 5.0 and a CISCO 3845. We set up a SIP Trunk between CCM and 3845.
The 3845 is connected to an international link with an international H323 Gateway.
So call scheme is CCM -- SIP -> 3845 -- H323 -> SP H323 Gateway.
Call initiated from CCM reach (ringing) the endpoint on International H323 Gateway but the communication can't be established when answering.
Does someone has already encounter this.
Any help is welcome.

Are you using software based MTP on the CUBE?
Check MTP Configuration

What are you using for codecs?
Also, do you have the following commands:
voice service voip
allow-connections sip to h323
allow-connections h323 to sip

Do you have a firewall between 3845 and the ISP?

Hello ,
If your service provider works with H323 , why do you use SIP from your CCM to communicate with your router ?
Why don't you use all in H323 ?
Thanks
