asterisk users - Jan 2005 - DTMF digit dropping

I run an automated information retrieval system, using Asterisk. Fairly
often the system misses a dialed digit.  Our codes are all 4 digits, see
lots of logs with:

       4199  - OK
       530   - Invalid code
       330   - Invalid code
       5330  - OK

As callers experience skipped codes.  We're using Broadvoice SIP with
inband DTMF (and we've tried every possible setting or option related to
DTMF).  Anyone else getting similar drops?  Any solutions.

Is http://connect.voicepulse.com/ , using IAX, any better?

I'm having the same problem with Voicepulse connect using IAX2. So, no, 
it's not better IMHO. And I've been thinking about switching to SIP to 
see if the problem goes away (I'm very reluctant to do so though) but 
it's hard to know if the problem lies with Voicepulse (or Broadvoice in 
your case) or whatever CLEC terminates your inbound number.

FWIW I have experienced the problem with Asterisk 1.0.2 and now also 
with 1.0.5. It doesn't seem to be an Asterisk problem though because 
the vast majority must not be having any issues with DTMF recognition.
