Ali,
The behaviour of dialer-list is to define which traffic will be
"interested" to trigger the DDR. If you deny sap/rip/457, all of these
traffic will be "un-interested" and therefore no call is made.
Once you try to ipx ping the peer isdn interface, since the IPX ping is
"permitted" at the dialer-list, this condition will trigger the DDR and
ISDN make a call.
Once the channel is connected, all the RIP/SAP/457 (or anything you denied
at the dialer-list) will go thru the ISDN.
The dialer-list is *NOT* a filter of anykind, it only use to define which
condition will trigger the DDR.
Of course, if your access-list 900 is applied to an interface (such ipx
output-network-filter), then it is really become a protocol filter.
Rgds,
