Sofia-sip and SpanDSP Notice!
Sofia-sip and SpanDSP dependencies have been removed from the FreeSWITCH? tree since v1.10.4 Release (05 August 2020).
You can find source files of Sofia-sip here:
https://github.com/freeswitch/sofia-sip
SpanDSP sources are here:
https://github.com/freeswitch/spandsp
Packages for Sofia-sip and SpandDSP are available for all supported platforms from our packaging repos.

In case of errors about "no usable spandsp" or sofia-sip, compile and install spandsp and sofia-sip first, then
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
where ls /usr/local/lib/pkgconfig should list at least
sofia-sip-ua.pc spandsp.pc
Then FreeSWITCH should compile properly.

yum install autoconf automake libtool openssl* libtiff* libjpeg*

git clone https://github.com/freeswitch/sofia-sip
cd sofia-sip
./bootstrap.sh
./configure
make
make install

git clone https://github.com/freeswitch/spandsp
cd spandsp
./bootstrap.sh
./configure
make
make install

export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

yum install -y https://files.freeswitch.org/repo/yum/centos-release/freeswitch-release-repo-0-1.noarch.rpm epel-release
yum install yum-utils
yum-builddep -y freeswitch --skip-broken
yum install -y yum-plugin-ovl centos-release-scl rpmdevtools

cd /usr/local/src
git clone -b v1.10.5 https://github.com/signalwire/freeswitch.git freeswitch
cd freeswitch
./bootstrap.sh -j
此时可以编辑配置需要编译的freeswitch模块，可以关闭不需要使用的模块。此处我注释掉了mod_av和mod_signalwire
./configure
此处如果遇到“no usable spandsp”异常时，按照官方指示设置下环境变量，之后重新configure
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
make
make -j install
make -j cd-sounds-install
make -j cd-moh-install
