Hi guys:

Remember those DID line conversion cards that we were going to order a
while ago?  Well, we have three of them.  I put two in an old server with
an
ISA backplane and they work pretty much as advertised.  They generate -
48V themselves, autoconfig to the DID line, etc.  There are, however, some
issues;  the biggest one being that the Asterisk server can't pick up the
line
when the DID card rings it.  Right now we're using one of the cheap X-101p
FXO cards to test with because I still have to justify ordering a
multiport
card.


Peter,  I don't have any specific experience with your issue but it
interested me so I did some googling.  I know that ringing is one of those
things that supposed to be something very specific and it's suited to analog
systems.  Digital systems have a hard time reproducing that 'ringing' and
some do it better than others.

Here's a discussion I found that might help:
http://www.voipuser.org/forum_topic_1791.html

Of particular interest to me was the discussion of a system that pulses
positive DC rather than sending proper AC to indicate ringing.  Apparently,
Asterisk does not detect this pulsing as a ring.

I don't remember seeing anything in zapata.conf that would 'loosen up' the
ring detection.

Are you in PEI, or are you local?

Dave
