In isdnd.rc you have to add:
---snip---
connectprog             = "your_prog_or_shell_script"
---snip---
(there's also a "disconnectprog") to your dial on demand entry.

After that you can put everything you want into
/etc/isdn/your_prog_or_shell_script, e.g.:
---snip---
#!/bin/sh

# $1 = -d
# $2 = <interface>
# $3 = -f
# $4 = <up/down>
# $5 = -a
# $6 = <IP-Address>

if [ "X$1" != "X-d" -o "X$3" != "X-f" -o "X$5" != "X-a" -o "X$6" = "X" ]; then
        # I'm awaiting the correct commandline!
        logger -t ISDN connectprog called without correct commandline!
        exit 1
fi

if [ "X$4" != "Xup" ]; then
        # what shall I do?
        logger -t ISDN connectprog called with param4 = $4
        exit 1
fi

# do your stuff here
---snip---

Bye,
Alexander.
