Summary:                    Zaptel: No Audio After First DTMF
Description: 
When calling into asterisk with Zaptel 1.4.6 the call answers fine, after
pressing a dtmf, the audio stops and asterisk does not see the dtmf.  Press
a dtmf a second time and asterisk will see it and play another file but you
cannot hear the audio.

This all works fine with Zaptel 1.4.5.1

We tried multiple Zaptel T410P's.

Note: The zaptel version below is incorrect, 1.4.6 is not selectable.

Like I discussed with Juggie, this sounds like an issue with the recent
rewrite of the wct4xxp driver and the VPM400M module with dtmf detection. 
I suspect by setting vpmdtmfsupport=0 as a module parameter, it will work. 
This is best handled by Digium Support though.
