You could use an extended access-list for something as simple as permitting all IP traffic, but you are more likely to make a mistake in your permit statement.
dialer-l 1 pro ip per ... does the job every time.
I typically use an extended access-list with a dialer-list if I am asked to only allow pings, or to keep EIGRP from keeping the link up. There is no demand-circuit command for EIGRP, and snapshot routing doesn't work with EIGRP, either.

Hello,
Speaking about CCIE wording with ISDN. When the question says that the
router should initiate and maintain an ISDN call if there is any IP traffic
destined for the other side of the link what would be the solution for this
?
Would it be : dialer-list 1 protocol ip permit
or
Would it be: dialer-list 1 protocol ip list 101
Where access-list 101 is pointing to the IP assigned to the ISDN interface
on the other side of the link?
It is always solved in the workbook the 1st approach but I just needed to
discuss why not approach number 2 also ?
Thanks for your time.
Yasser
