OK, so we are having CUCM 9.x and 2951 router with SIP trunk to PSTN. Router is set as h323 gateway for CUCM... Pretty simple configuration, nothing fancy, and everything is working as it should, but one thing.
After we are call someone outside who is using some sort of IVR(lets say you call your ISP, and first thing you get is IVR saying press 1 if you want to talk with sales, press 2 if you want to talk with IT...), connection is established, but after it, telephone doesn't react whatever number you are pressing. So after I get the message to press 2 to talk with IT for example, I can press 2 all day long, nothing would happen, I would still have innitial dialog...
Does anyone knows what is the problem with this, and where in configuration I could change it?
Mostly because I'm way over my head in voice over IP, so I used some similar configuration as my guide when I started, and there was h323 between CUCM and CUBE even though they too have used SIP trunk...
Also, have looked about similar dtmf mismatches, and what frightens me is that they were also using 7942 phones... But that was 3 years ago, and should've been solved by now.... Anyhow, big thanks on your response, helped me know where to look at I will try something tomorrow(looks like I have missed dtmf relay in one dial peer while configuring), and hopefully it will work.
When you get a chance also post your configuration, one thing to keep in mind is that all call flows use 2 dial peers (inbound and outbound) if you do not have an explicit inbound dial peer configured with proper dtmf method then hidden dial-peer 0 is used which is known to mess with things like this.
so, the story is still the same, and im out of the ideas... one important note though. after we get connected and hear "welcome to call center of....", after pressing a number, we can hear a sound of number being pressed, but we are not seeing anything on phone display ! all the phones are 7942.
this is what debug says in the moment when we press the number(i have upload of whole debug ccsip, ccapi and rtp session, but not sure how to upload it):
