I wonder if someone could give me some advise on the best way to configure a CUBE which is currently not working as expected, I have a CUCM cluster v5.x and a pair of CUBEs (configured as H323 gateways) connected via H323 (non gatekeeper) trunk to a service provider.
The problem i have is that on outbound calls I can setup a call and can see Tx and Rx packet counts going up on the ip phones but have no audio.........
I believe the problem is to do with MTP and I will need to configure MTP resources locally on the CUBE and terminate the 2 legs of the calls on the CUBE as the service provider's prefered codec is G729 I don't believe local (CUBE) transcoding is required.
My question is firstly has anyone done anything like this and is willing to share configuration, and secondly does this seem to be the correct route of investigation or am I missing something and should be concenrating else where?
You should not be needing any MTPs for this type of setup. Can you elaborate on your topology and what type of circuit is the telco providing? Is it a SIP trunk? Posting configuration would be helpful. Is your Region between the phone and CUBE configured to use G729?
How is routing performed, are you using NATing anywhere?
