Opensips

This guide uses a Debian 13 aarch64.

Opensips provides some apt repositories here. Unfortunately packages are only for x86 and Debian 12.

Sooo… let's build it from source.

Let's download code :

git clone --recurse-submodules https://github.com/OpenSIPS/opensips.git -b 3.6 opensips-3.6

Install ncurses for interactive compilation, and dependencies :

apt install -y libncurses5-dev flex bison libssl-dev

Ok let's configure and compile :

cd opensips-3.6/
sudo make menuconfig

Select compile and install opensips. When compilation and linking is over select Generate OpenSIPS Scripts, then select the most adapted script for your setup (me it was residential), then select your settings.
