[Asterisk-Users] How to determine line signalling?

[Brian Capouch]

I'm not quite sure where to hunt for the answer to this.  My apologies 
in advance if this isn't the appropriate forum.

I have generally speaking used Kewlstart signaling on the POTS lines 
that I have used with asterisk, with great success.

I have an installation where the POTS is coming from an in-house PBX 
(Panasonic TVS100) instead of the LEC, and on this one Kewlstart doesn't 
seem to work.

The extension goes "busy" (from the perspective of someone else on the 
PBX trying to call it) as soon as I plug it into the X100P, and when I 
have asterisk "pick it up" I hear a faint busy signal.

I tried Loop Start with the same result, but I'm kind of thrashing as 
far as how the files /etc/zaptel.conf and /etc/asterisk/zapata.conf have 
to synch.  When I tried to use Ground Start (set zaptel.conf "fxsgs") I 
get an error from ztcfg.

Is there some glaring thing I am doing wrong?

Thanks.
