[Freeswitch-users] Lost and delayed DTMFs

I was premature in thinking our problems were solved.  When we use 
inband with start_dtmf all of the navigation works well and we do not 
experience loss of dtmfs but recordings will not reliably terminate. and 
the terminator tone is recorded when it does. Sometimes 2 or three key 
presses will terminate sometimes 15 sometimes they have to hang up to 
terminate it.    When we change to use RFC2833
<param name="dtmf-type" value="rfc2833"/>
  <param name="liberal-dtmf" value="true"/>
  The recordings always terminate correctly, but we have major dtmf 
loss.  Does anyone know what we should try to do to solve this?
Thanks,
  Jack
