Ok, so the fact that a tone can be heard, although only partially, would suggest inband digits are being sent too.  I'll speak to my carrier and see if it is something they can supress their end.  
Thanks for the help and the tips on debugging :)

Thanks

To listen to the audio:
In wireshark, go to telephony -> voip calls -> wait a second -> click select all -> player -> decode -> check the box for both channels -> play, to listen to the actual call.

Hi Avi,

thanks for the tips, wireshark & tcpdump are great! 

I have collected the PCAP file after making a call and can see the RTP events that show the tones being sent.  How do I now determine if an inband tone is also being sent?

thanks
Matt

Once you get a PCAP, you can open it up in wireshark.
Then, you can put in the filter: rtpevent.
That will show you rfc2833 that comes in.

Then you can go to telephone -> voip calls -> wait a second -> click select all -> player -> decode -> check the box for both channels -> play, to listen to the actual call.

Thanks Steve, thanks nick. Ill take a look at those links :)

Is there anything in particular I should be looking out for to see if any inbound is sneaking in? 

Again Thanks for the help
Matt

PCAP is the file format used by packet capturing tools such as tcpdump, Wireshark, tshark (Wireshark's command line tool), ngrep and a host of others.

Hi Avi

thanks for your response.

Sorry I'm quite new to Freeswitch/linux, what is a PCAP?
I was leaning towards it being the carrier as omitting dropt_dtmf results in the full tone being transmitted. My issue is that I cannot see how to test is this in fact the case.

Using the dialplan shown in my original emails and setting the log level to 7, when making the call I can see the DTMF tones coming in but am unsure if this is the inband being reported or the out-of band.

thanks
Matt
