With ISDN Debian suggests the following:

#
# This script is run by the pppd after the link is established.
# It uses run-parts to run scripts in /etc/ppp/ip-up.d, so to add
routes,
# set IP address, run the mailq etc. you should create script(s) there.
#
# Be aware that other packages may include /etc/ppp/ip-up.d scripts
(named
# after that package), so choose local script names with that in mind.
#
# This script is called with the following arguments:
# Arg Name Example
# $1 Interface name ppp0
# $2 The tty ttyS1
# $3 The link speed 38400
# $4 Local IP number 12.34.56.78
# $5 Peer IP number 12.34.56.99
# $6 Optional ``ipparam'' value foo
# The environment is cleared before executing this script
# so the path must be reset
PATH=/usr/local/sbin:/usr/sbin:/sbin:/usr/local/bin:/usr/bin:/bin
export PATH
# These variables are for the use of the scripts run by run-parts

PPP_TTY="$2"
PPP_SPEED="$3"
PPP_LOCAL="$4"
PPP_REMOTE="$5"
PPP_IPPARAM="$6"
export PPP_IFACE PPP_TTY PPP_SPEED PPP_LOCAL PPP_REMOTE PPP_IPPARAM
# as an additional convenience, $PPP_TTYNAME is set to the tty name,
# stripped of /dev/ (if present) for easier matching.
PPP_TTYNAME=`/usr/bin/basename "$2"`
export PPP_TTYNAME
# Main Script starts here
# Do not want the ip-up.d scripts for an inbound connection.
if [ "$PPP_IPPARAM"X = inboundX ]; then
