[Asterisk-Users] TDM400P + FXO module = PSTN woes

The above looks different then my setup, and is likely the result of a
previous asterisk installation.

The "install wcfxs" was replaced several months ago with "install wctdm"
and the "alias wctdm wcfxs" was replaced with "alias wcfxs wctdm". 
Those statements are part of the reason for our confusion. I'd suggest
them with this:
 install wcfxo /sbin/modprobe --ignore-install wcfxo && /sbin/ztcfg
 alias wcfxs wctdm 
or look through the code in /usr/src/zaptel to confirm.

The above is why your lsmod is showing wcfxs and not wctdm.

What does "zap show status" indicate?

Also, what does the CLI show when you dial a call that is suppose to
go out the TDM card?

Yes, I see that once in a while also.

The above is good.

Now I'd start looking at the exact extensions.conf entry that is
supposed to be executed when you place a call.

Copy/paste that part and include the CLI stuff as noted above.

FWIW, I don't use a threaded email reader, so don't delete to much from
the above in your reply, or I'll forget what you previously stated.
