asterisk users - May 2005 - 1800 DNIS and asterisk (HOW TO?)

DNIS is dialed number identification service.  With toll free services,
the carrier will send DNIS digits (to your PBX) to identify which toll
free number was called.  The DNIS sent from the network to your PBX may be
4 digits long for example.  I suspect that you will need to build an
extension matching whatever DNIS they are going to send to your PBX when
the toll free number is dialed.  I'm guessing that is what they were
trying to explain.

Hi
I have applied for Qwest 1800 termination to a T1 ISDN PRI. They tell me
that I will have to program a predefined DNIS number on my switch.
According to them unless asterisk returns that DNIS number no call will
get through.

How do I program the DNIS, is it through zaptel.conf or some other way. Is
it required??. As per qwest "if the 8xx # is going to be routing to an
ISDN TG, DNIS is required".


Will appreciate any help
Regards

Huh?  The last time I dealt with DNIS (admittedly, years ago) the
provider sent the digits to ME via DTMF to tell ME what number was
dialed to terminate on that line (you know....Dialed Number
Identification Service).

Unless DNIS has turned into telcoBGP while I haven't been watching, what
you're being asked to do doesn't seem quite right.

Hi, anyone know of a default driver option that could be set so that  an 
incoming pstn call on my fxo interface would be forwarded/bridged to 1 or 
more fxs interfaces and vice versa.

Would be nice to have a fail-open option, whereby a phone connected to the 
fxs interface could still make/receive calls via pstn if asterisk was shut 
down due to some problem.

regards

Mark
