If you call from X-Lite to the demo menus can you hear them clearly (no
choppy sound)?  Given the problems you are having this might point to a
bad TDM100P card.  I recently had to swap out a TDM100P card (rev H) for
a replacement (rev G) card because the card apparently wasn't supplying
correct
timing for Asterisk.  This even affected X-Lite to demo calls where the
FXO and FXS modules weren't even being used.  The way to check is to switch
to
the ztdummy driver instead of the TDM100P driver and see if the X-Lite ->
demo
calls become clear.  I don't know if was a defective card or a REV H issue,
but
now at least working.  The other symptoms in my case were no dialtone through
the FXS card and the FXO card not answering incoming calls.

Hi,

o I purchased 3 TDM31B cards and fixed them in my computer (in 3 PCI
  slots)

o I downloaded the latest Zaptel source from CVS, compiled it and loaded
  modules zaptel.o and wctdm.o.

o I successfully configured them from /etc/zaptel.conf as
  shown in the information below.  ztcfg returned no errors - see the
  report below.

o I successfully configured /etc/asterisk/zapata.conf (see info below).

o I configured an X-Lite phone to test with an analog phone plugged into
  one of the channels.


The problems are:

o I cannot make a call from the analog phone (Saachi phone, KX-T3223)
  connected to one of the FXS ports.  When I pick up the receiver, I hear
  the dialtone but when I press the buttons, asterisk seems not to get the
  numbers dialled, both using pulse and touch tone dialling.

o I can call the analog phone from X-Lite however on receiving, I cannot
  hear much voice.  What I hear is choppy sound corresponding to whatever
  I say from the analog side.  When someone speaks from the X-lite side,
  nothing is heard from the analog phone.

o There are three FXS ports where there is no dialtone - but the phone is
  actually powered - I can hear touch tone / pulse when I dial.

o There are three FXS ports that give neither power nor dialtone.

What could the problem be?  Any help will be highly appreciated.  Please
find below abit of information I thought may be useful.  Please let me
know if more is needed.
