I think Hellmuth choosed a good value for rtprio, and I didn't think it
solves your problem if you increase the value, but feel free to play a
little bit with it (I think isdnd slowes down because of a lot of
interrupts, and if I didn't have a wrong understanding of the system,
rtprio didn't helps in this case).

What's your defaultroute? I use "-interface isp1".
BTW: I use /etc/start_if.isp1 to configure the interface, no need to
modify rc.isdn, e.g.:
---snip---
(11) root@ttyp0 # less /etc/start_if.isp1
ifconfig isp1 link1 0.0.0.0 0.0.0.1 netmask 255.255.0.0
ispppcontrol isp1 $(cat /etc/isdn/connect-CBC.parameters) enable-vj
ifconfig isp1 down
---snip---.
While we're at it, maybe someone wants to commit something like this:

(I think the isdn_ttype part isn't needed anymore, someone committed
something like this already, but the screenflags part is useful for me)
Bye,
