Installing required components and libraries

All components, incl. and FreeSWITCH download and install from the directory /usr/local/src/
Install Libks:

git clone https://github.com/signalwire/libks.git /usr/local/src/libks
cd /usr/local/src/libks
cmake .
make && sudo make install

Chek install libls:
ldconfig && ldconfig -p | grep libks

If libks is not installed, there will be no output. If it is installed, you will get a line for each version available.:

root@pi:/usr/local/src/libks# ldconfig && ldconfig -p | grep libks
libks2.so.2 (libc6,hard-float) => /lib/libks2.so.2
libks2.so (libc6,hard-float) => /lib/libks2.so
libksba.so.8 (libc6,hard-float) => /lib/arm-linux-gnueabihf/libksba.so.8
root@pi:/usr/local/src/libks#

Install signalwire

git clone https://github.com/signalwire/signalwire-c.git /usr/local/src/signalwire-c
cd /usr/local/src/signalwire-c
cmake .
make && make install

Chek install signalwire
ldconfig && ldconfig -p | grep signalwire

Install Sofia SIP

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

verification:
ldconfig && ldconfig -p | grep signalwire

Install Spandsp

I have mistake, when I make FS according to the official instructions(mod_spandsp_dsp.c: In function 'get_v18_mode':
mod_spandsp_dsp.c:159:10: error: 'V18_MODE_5BIT_4545' undeclared (first use in this function)
159 |  int r = V18_MODE_5BIT_4545;),
I make next steps:
git clone https://github.com/freeswitch/spandsp.git
cd spandsp/
git checkout 0d2e6ac
./bootstrap.sh
./configure
make && make install

verification:
ldconfig && ldconfig -p | grep spandsp

Install and build FreeSWITCH

Download FreeSWITCH 1.10.11 release in /usr/local/src directory and unpack

ln -s /usr/local/freeswitch/bin/fs_cli /usr/bin/fs_cli 
ln -s /usr/local/freeswitch/bin/freeswitch /usr/sbin/freeswitch

Create a unprivileged system user for running FreeSWITCH daemon
groupadd freeswitch 
adduser --quiet --system --home /usr/local/freeswitch --gecos 'FreeSWITCH open source softswitch' --ingroup freeswitch freeswitch --disabled-password 
chown -R freeswitch:freeswitch /usr/local/freeswitch/ 
chmod -R ug=rwX,o= /usr/local/freeswitch/ 
chmod -R u=rwx,g=rx /usr/local/freeswitch/bin/*
