I'd recommend getting a pcap of the incoming call and then listen for DTMFs in the audio stream using Wireshark. If you don't hear the DTMFs in the pcap then you know that the digits aren't even making it to you and that you'll need to talk to your carrier. If the DTMFs are present then you will need to dig a little deeper on your end.

Hi folks,

What would cause DTMF to suddenly stop working on inbound calls? I have a relatively simple setup with folks diallg in and navigating through an IVR menu. I'm using start_dtmf in the dialplan and I can see this being called at the start of the call. Basically everything was working fine before the weeked, nothing has changed though we did have some problems with our internet connection and now none of the dtmf tones in the incoming calls are being indentified by freeswitch. Any clues?

Many thanks Andy
