Trying to test FS voicemail with sipp. 

I can't get DTMF to work no matter which way I play it.  Any tips?

If I use "start_dtmf" in my dialplan, and send DTMF with "play_dtmf" in my sipp scenario they should go in-band, right?

And likewise if I take out "start_dtmf" and use "play_pcap_audio" with the 2833 pcap files in my scenario it should go out of band, right?

Neither work.

Attaching my scenario file.  Maybe I'm just not doing it right?
