If your DTMF detection is sketchy then I would record the calls and listen to them. You need to make sure that the tones are coming through cleanly. From the symptoms you've described I have to wonder if the issue is with the network or provider and not your FreeSWITCH box.

Thanks for your reply, Michael. I have tried doing a start dtmf but then I've noticed:

1.  My skype key presses get unreliable...
2. The dtmf detection is patchy with inband -- works sometimes and doesn't work sometimes :-)

Any settings to keep in mind apart just adding a start dtmf ?

Thanks,

Sidharth

Sidharth,

A mobile phone will always send DTMFs in-band, so you need to be ready for that scenario. I recommend you add this to your dialplan for inbound calls:

Test various scenarios and make sure they work - call from Skype, from mobile phone, from a land line, etc. Let us know what happens.

Dear Friends,

I'm using a voip carrier Voicenetwork.ca (recommended by someone on this list). While I'm generally happy with their service there seems to be one fatal problem: My IVR does not recognize DTMF!

I have set <param name="dtmf-type" value="rfc2833"/> in both sip_profile/internal.xml and sip_profile/external.xml

The symptom of the problem is that making a call via skype will always make the IVR recognize the DTMF while using something like a mobile phone almost always won't!

I've tried in-band detection too. I'm making international calls into my IVR and the reliability of the in-band detection is not so good, possibly because of the quality of the call.

Can someone please help me?

Thanks,

Sidharth
