I am on dialup and my call to pppd is very similar.  I have the "defaultroute"
but don't have "noauth", "passive", or "asyncmap 0".  I'm not sure why you
have the "passive" but it shouldn't affect your routing.

What distribution are you using?  If it is RedHat, make sure that you don't
have a "GATEWAY=xxx.xxx.xxx.xxx" line in your
/etc/sysconfig/network-scripts/ifcfg-eth0 file.  I think you are setting a
default route before you dial the phone and I don't think pppd likes to
change that.  What does route -n look like before you dial?
