[Asterisk-Users] Immediate routing on "0" (DNIS)?

[Ken D'Ambrosio]

I've got a T1 (E&M wink).  Our four-digit inbound DNIS numbers are in the
range of 0600 - 1699.  However, the second that the "0" is seen on an
in-bound 06xx call, it stops listening for any more digits, and
immediately tries to route the call.  My 16xx numbers wait for all four
digits before trying to route.  Is there something, somewhere, that tells
it to do an immediate route on seeing "0"?  I don't have much of anything
in my extensions.conf file.  I'm seeing what's going on via
"tail -f /var/log/asterisk/full"

Any suggestions?

Thanks!
