This is there.

This was taken out when I reduced the options, it's back in.

Waiting a bit for 1.2, not yet ready to rewrite the dial-plan.

[globals]
TRUNK=Zap/g0    ; Trunk interface
TRUNKMSD=1      ; MSD digits to strip (usually 1 or 0)
[localexchange]
exten =>
_9NXXXXXX,1,DBput(RepeatDial/${CALLERIDNUM}=${EXTEN:${TRUNKMSD}})
exten => _9NXXXXXX,2,Dial(${TRUNK}/${EXTEN:${TRUNKMSD}})
exten => _9NXXXXXX,3,Congestion

The above is working just fine with the Digium X101P FXO cards and
has for the last year and 1/2.

Looking at the X101P when it dials out, it starts at 46.6 volts,
then drops to 8.7 when it dials the DTMF digits, repeated for 10
observations.  No reversal or dropping to 0 noted.  Switching
to the ADIT 600 FXO card there is 50 volts while not connected
dropping to 10 when it dials.

I have found two things.  The first was one of the POTS lines
was wired with tip/ring reversed by the telco.  The second
was that only one of the three lines wouldn't work for
outbound calling (only one DTMF digit is sent).  Noticed that
one line is wired next to the ADSL line for Internet service.
Temporary disconnect of the DSL the line, it works, my test
set reported finding data signals on the line also. So it
would appear that the ADIT 600 doesn't tolerate the
interference.

So for now I've moved two POTS lines to the ADIT 600 and left
the one connected to the X101P.

I'm sure it's going to cause confusion that one line is
directly on the PBX however the others go though the ADIT.

I'm not entirely certain that everything is OK however
I think we can move forward.  I still have to figure out
why Span 1 stopped functioning (shows the Nop state),
btw. the F1 detail in zttool states "Not Open" instead
of "Not Operational", perhaps a typo?

Thanks very much for your assistance, it was a very frustrating
problem for me.

Kind Regards,
William.
