I would suggest either:
1) Turn on authentication (at least have the called side authenticate
the calling side), or
2) Add the dialer string on the called side, make all traffic
uninteresting on the called side and disable the 'dialer idle-timeout'
on the called side.

Subject: Re: isdn: no dialer-group, no good?
I have also ran into something interesting in the last couple of
days....with only 2 weeks left from today until D-day
I am using dialer map statements on my calling and receiving routers and
have an interesting problem. On my calling router I have the following:
R1---calling router
int bri 0
ip address 133.1.100.5 255.255.255.252
encap ppp
dialer map ip 133.1.100.6 name router2 broadcast 5552222
dialer-group 1
dialer-list 1 protocol ip permit
R2----receiving router
int bri 0
ip address 133.1.100.5 255.255.255.252
encap ppp
dialer map ip 133.1.100.5 name router1 broadcast
dialer-group 1
dialer-list 1 protocol ip permit
When I use the above configs the calling router is not able to ping the
remote router. However if I add a dial string to the end of the dialer
map
on the receiving router the ping works fine. This is not what I am
after
though. I do not want to the receiving router to have a dial string,
because I don't want it to be able to initiate a call.
Any suggestions?
Any input is appreciated.
Thanks,
David
