Hi Chris,

Another option would be using a dialer rotary group on the remote site.
To your problem about not getting an answer on your ping, there is most
likely a problem with authentication.

Hi,

I would be greatful if anyone could assist me with a very basic ISDN query.
If a task specifies that a call should only be initiated by one end of the
link, I'm trying to sort out exactly what options are available to satisfy
this.

I'm only aware of two ways. One is to omit the "dialer-group" from one end
so no interesting traffic is specified and the other is to remove the dial
string from the "dialer map" statement at one end so it can't physically
dial out. Are there any other obvious techniques.

Also, assuming I have a "dialer-list 1 proto ip permit" and "dialer-gr 1" at
both ends but I omit the dial string from one of the "dialer map"
statements, the link comes up in one direction as desired but ping won't
work even though the link is up. Why is this?

Thanks,

Chris
