An open example implementing a SIP server for an intercom
To deploy project, create file deploy/.env from example, adjust settings and use deploy.sh from the project root.
Following ports should be accessible on server:
- 80 (for HTTP)
- 5060 (for SIP)
- 16000-16999 (for RTP media)
After deploy, frontend and SIP over WebSocket will be on HTTP port 80 on the server. It's preferred to set up proxy with HTTPS in front of it.
The client app should navigate to https://{PROXY_URL}/?user={USER_NUMBER}&password={USER_PASSWORD}&domain={EXTERNAL_IP}&url={WS_ENDPOINT}.
External IP could be acquired by running command docker exec -it doma-freeswitch-1 /usr/local/freeswitch/bin/fs_cli -x 'sofia status profile internal' on deployed server in field Ext-RTP-IP.
For example, if your server is deployed on IP 192.168.10.42 and is behind proxy on https://sip.example.com/
user = 1000
password = 1234
domain = 192.168.10.42
url = wss://sip.example.com/sip (Note wss instead of https)
All url parameters should be url-encoded.
Prepare .csv file with pairs of number,password of users, and run cd scripts && node importUsers.js /path/to/users.csv. This script will import users in running instance of the server.
Note: if container was rebuilt, it's required to import users again.
