# ENFORCE THE TRANSPARENT CODEC FOR ISDN UD-64 CALLS
#
# Sample configuration of context CS only. Without gateway and IP
# configuration.
#
# After replacing all variables you may copy and paste this
# configuration part into your offline configuration file.
#
# Incoming ISDN calls will be split into two call-router paths to
# enforce transparent codec for ISDN unrestricted digital calls.
# Note that the VOIP-DATA interface has no route into the
# call-router, it operates as a one-way interface. But it has a
# special Voip-Profile linked, which only contains the
# transparent codec.
# The VOIP-DEFAULT interface will be used for incoming voip calls.
# It uses the default voip profile, which is linked in the voip
# gateway. The default profile contains the transparent codec
# with the lowest priority to ensure that voice calls never uses
# the transparent codec.
