I agree with Scott, the dialer-list only decides what traffic can make the
call happen. Once the call has happened then any traffic can cross it.
However (you may already know this..) the dialer-list also defines what
traffic to monitor when the call is active - i.e. in relation to the idle
timer.
For example, if you exclude netbios traffic from initiating the call, when
the line is up netbios traffic will still cross over the line (every 40
seconds). But, as this netbios traffic is classed as NOT interesting the
router will not consider it when monitoring the idle status of the line, and
it will have no impact on the idle timeout.
i.e. access-list 100 deny udp any any eq 137
access-list 100 permit ip any any
dialer-list 1 protocol ip list 100

Subject: dialer-group question
The dialer-group is ONLY used to select interesting traffic to bring up
ISDN line, or it is also used to decide which traffic can go through
after the line is UP ?
In my test, I have the following:
access-list 104 permit icmp any any log
dialer-list 1 protocol ip list 104
After the line is up, I see all kinds IP traffic, like BGP, go through
the line. Looks like dialer-group is ONLY used to bring up the line ?
