[hylafax-users] multitech modem dropping DTMF digit

[Christopher <chrismcc@xxxxxxxxxxxxxxxx>]

Hello...

 I have and existing hylafax setup that has been working well for a
while (years but with slightly different setups).  The current
incarnation is a PRI -> cisco router (conf below) -> VWIC -> modem ->
hylafax(4.4.4).  I get DTMF and can route the fax using the called
number.   The Hyla fax config is below.

Now I am trying to add a second modem, but it seems to miss the second
digit in the DTMF stream.  The new modem is a MultiTech MT5656ZDXV and
minicom output is below


The fax number in this example ends in 498.  The modem only gets the
first and last digits.
syslog:

Mar 23 12:10:07 qwip FaxGetty[20881]: STATE CHANGE: LISTENING ->
ANSWERING




Question goes here:

Does anyone know why this multitech modem cannot get the DTMF data?
When looking at a call with minicom the output seems "funky".

no defense.  I tried it.  Only tinfoil works.
