wget https://github.com/signalwire/freeswitch/archive/refs/tags/v1.10.12.tar.gz
tar -zxvf v1.10.12.tar.gz
cd freeswitch
./bootstrap.sh -j

Edit Module files as per your requirements

vim modules.conf

• enable mod_xml_curl
• enable mod_curl
• enable mod_shout
• disable mod_signalwire

./configure --prefix=/opt/freeswitch

Faced this issue while compiling the code

vim ./src/mod/applications/mod_spandsp/mod_spandsp_dsp.c

Edit file as per the above-mentioned GitHub Issue.

make
make install
ln -s /opt/freeswitch/etc/freeswitch /etc/freeswitch
ln -s /opt/freeswitch/bin/freeswitch /usr/bin/freeswitch
ln -s /opt/freeswitch/bin/fs_cli /usr/bin/fs_cli
useradd -M freeswitch
mkdir -p /opt/freeswitch/run/freeswitch/
chown -R freeswitch:freeswitch /opt/freeswitch

Now create a Service file

vim /etc/systemd/system/freeswitch.service

copy the following content in the file
