Both sides need to dial in to the isdn switch, so it makes sense that both
sides need to know the number to dial.
To have only one side capable of "initiating" a call, it seems that you
would only put a dialer-list on one side (or a very restrictive dialer list
on the side that doesn't initiate calls).
Thank you,

If you are running a routing protocol like an OSPF demand circuit you
should only need a dialer map on the side that you want to initiate the
call.
You need to allow for interesting traffic on both sides though.
At least that is the way that I have been doing it.

Hello Group,
I'm having a little confusion here regarding ISDN dialing out only from
one
side, so the other side is not allowed to initate a call. From what I
have
tested before, the dialer statements below should work.
dialer map ip 138.1.35.2 name R5 broadcast
dialer map ip 138.1.35.1 name R3 broadcast 2222
But the only way I can get pings to reply is by adding a number at the
end
of the first dialer map:
dialer map ip 138.1.35.2 name R5 broadcast 1111
R5 does dial out and establishes connection, but it looks like R3 does
not
know how to respond.
Am I missing something?
Albert
