Provide self hosted STUN and TURN services in order to allow SIPSoftphone calls, AudioChat, VideoChat, DesktopSharing sessions for ProCall Enterprise clients (Windows and Mobile) to function regardless of firewall limitations.
- a Docker Enabled Linux Machine with min. 2 vCPU, 4GB RAM and 20GB Disk
- a public IP address assigned directly to the Machine or via a 1:1 NAT
- The following open/forwarded firewall ports:
- 3478/TCP
- 3478/UDP
- 49152-65535/UDP
Quick start:
# curl -sSL https://get.docker.com | sudo bash -
docker run -d --name stunturn --network host --restart always \
-e EXTERNAL_IP_ADDRESS=YourExternalIPAddress \
-e LISTENING_IP_ADDRESS=YourLocalIPAddress \
-e TURN_PORT=3478 \
-e TURN_USERNAME=YourTurnUsername \
-e TURN_PASSWORD=YourTurnPassword \
estos/stunturn
In order to get configuration info, use the following command:
docker logs stunturn
The first ~10 lines will contain useful configuration information for your UCServer. E.g.
No TURN_PORT env variable set. Default 3478 UDP and TCP will be used
No TURN_USERNAME env variable set, user will be set to 'stunturn' and password will be randomly generated
Created TURN user 'stunturn' with password 'RLYmta9lTFQM0ClqECWq'. Please use said credentials into your estos application
Executing TURN service...
Your STUN and TURN server is now running
Please configure your estos UCServer own STUN and TURN servers according to the following template:
STUN Server --> stun:1.123.456.254:3478
TURN Server --> turn:1.123.456.254:3478
TURN username: stunturn
TURN password: RLYmta9lTFQM0ClqECWq
Logs are stored in local file within the container in the following name format: /var/tmp/stunturn_DD_MM_YYYY.log
To list them run:
docker exec stunturn ls /var/tmp/
to print out a specific one (e.g. from 26/04/2022):
docker exec stunturn cat /var/tmp/stunturn_26_04_2022.log
Log level is, by default, set to "normal".
More verbose log levels can be set with the LOG_LEVEL environment variable (see details below).
