patch -p0 --ignore-whitespace < $BUILDDIR/audio.patch       # Provisional patch for https://github.com/signalwire/freeswitch/pull/1531

# Patch: https://github.com/signalwire/freeswitch/pull/1914
#   There are some long-standing issues with the way FreeSWITCH changes
#   candidate pairs based on connectivity checks. That generally manifests
#   as: 1) an asymmetric start time between inbound and outbound audio (eg
#   inbound audio takes 20 seconds to come in while outbound works right out
#   of the bat 2) wrong pairs being picked initially and FS taking longer
#   than ideal to find a new one 3) 1006s 4) ...
#
#   This ports signalwire/freeswitch/pull/1914 in an attempt to mitigate
#   the aforementioned issues. The PR description explains the rationale
#   rather well and seems sound.
