I'm guesing you have xntpd_enable="YESS" in /etc/rc.conf? If so, set it
to "NO", issue `killall ntpd' now, and it will stop dialling in for you.
I don't use ISDN, but I'm sure there must be some way of triggering a
script once the interface is started and the link established. Use
ntpdate, or better, ntpd -q, to synchronise your host's clock.
