Brian,
I was hoping for the router to try the second number because the first
was unavailable. I got that idea from:
The dialer interface has two dialer strings. Remember that there are two
BRI interfaces on the remote router (torito). Since those BRIs were not
configured in a hunt group by the Telco, router melanie must dial each
BRI individually. With multiple dialer strings, the first phone number
is always dialed. Only if that call fails does the dialer interface try
the second dialer string. We can define as many dialer strings as
necessary as they are used in sequential order.
and many other places.
Configuring the Adtran for supporting two calls to 3333000 would only
mask the problem....
