Kamailio is an Open Source SIP Server released under GPL, able to handle thousands of call setups per second. Kamailio can be used to build large platforms for VoIP and realtime communications – presence, WebRTC, Instant messaging and other applications.

kamailio.org

Before first run need to prepare kamailio default config files. If you already have kamailio config files, then you can skip this. To prepare default config files need to execute

docker create --name kamailio kamailio/kamailio-ci
docker cp kamailio:/etc/kamailio /etc
docker rm kamailio

Then you can start docker image

docker run --net=host --name kamailio \
           -v /etc/kamailio:/etc/kamailio \
           kamailio/kamailio-ci -m 64 -M 8

You can use this systemd unit file on your docker host. Unit file can be placed to /etc/systemd/system/kamailio-docker.service and enabled by commands

systemd start kamailio-docker.service
systemd enable kamailio-docker.service

If you use debug image, then need map host directory (or volume) to contianer /var/lib/coredump folder. This may be done using additinal docker run option -v /var/lib/coredump:/var/lib/coredump

Requred to create user defined network first.

docker network create --driver bridge  --subnet 10.0.0.0/24 my-net

Or you can create swarm network

docker network create --driver overlay --attachable --subnet 10.0.0.0/24 my-net

Then you can create systemd unit file
