# Suppose that we have a PSTN gateway with IP address 1.2.3.4
# We should prevent REGISTER messages that contain that IP
# address in Contact header field because that can cause serious
# security hole (a malicious user might be able to register such
# a contact and bypass security checks performed by the SIP proxy).
#
# The following line prevents registering Contacts with IP 1.2.3.4
# (Don't forget to list also all hostnames that can be used to
#  reach the PSTN gateway)
#

ALL : "^sip:.*1\.2\.3\.4$"
