Sofia-SIP 1.13.17

Sofia-SIP 1.13.17

This is the exact Sofia-SIP version used by GABPBX.
GABPBX's chan_sofia SIP channel driver is built and tested against Sofia-SIP v1.13.17, and the
GABPBX documentation pins this tag. Use this release to build a GABPBX that matches the tested stack.

The upstream Sofia-SIP v1.13.17 release, published in this fork
(garacil/sofia-sip, a fork of
freeswitch/sofia-sip) so GABPBX builds are pinned and
reproducible against a known Sofia-SIP version.

Build it into /usr/local before building GABPBX (chan_sofia links against
/usr/local/include/sofia-sip-1.13 and /usr/local/lib/libsofia-sip-ua):

git clone https://github.com/garacil/sofia-sip.git && cd sofia-sip
git checkout v1.13.17                 # the version GABPBX chan_sofia is built + tested against
./bootstrap.sh                        # only if ./configure is missing from the checkout
./configure --prefix=/usr/local
make && sudo make install && sudo ldconfig
