WebRTC
WebRTC/WebSockets/WSS
WebRTC is supported from MOR X18 (with PJSIP enabled)
Requirements
- Asterisk-20
- Rocky OS 9
- MOR X18 (or later)
- Domain name
- TLS (SSL) certificate
Enabling WebSockets (WS/WSS)
1. In Asterisk servers edit /etc/asterisk/http.conf and make sure that these settings are configured under [general] section:
[general] enabled=yes bindaddr=0.0.0.0 bindport=8088 tlsenable=yes tlsbindaddr=0.0.0.0:8089 tlscertfile=/path/to/certificate tlsprivatekey=/path/to/private_key
Note: these settings should be already present in http.conf, but commented out. Just uncomment required settings.
Set proper path to TLS certificate in tlscertfile and private key in tlsprivatekey.
2. Restart Asterisk:
systemctl restart asterisk
3. Check if http configuration is applied:
asterisk -rx "http show status"
The output should be similar to this:
HTTP Server Status: Prefix: Server: Asterisk/20 Server Enabled and Bound to 0.0.0.0:8088 HTTPS Server Enabled and Bound to 0.0.0.0:8089 Enabled URI's: /httpstatus => Asterisk HTTP General Status /ws => Asterisk HTTP WebSocket
The important parts are:
HTTPS Server Enabled and Bound to 0.0.0.0:8089 /ws => Asterisk HTTP WebSocket
If these are present, it means that Asterisk is configured to accept calls via WebSockets protocol.
4. Check if Asterisk is accepting HTTP request:
In browser, open the following address (with your own domain address):
https://YOUR_DOMAIN:8089/httpstatus
The output should be similar to this:
If this page is shown, Asterisk is configured to work with WebSockets protocol and WebRTC calls can be initiated using address:
https://YOUR_DOMAIN:8089/ws
Enabling WebRTC in PJSIP Devices
Only PJSIP Devices are allowed to make WebRTC calls.
In PJSIP Device settings, enable WebRTC option under Advanced settings:
MOR X17 (or older) WebRTC/WebSockets/WSS
WebRTC together with MOR can be integrated using 3rd party solutions (Example: https://www.mizu-voip.com/Software/WebRTCtoSIP.aspx).
With Asterisk 1.8: Please note that only audio could work, because in our experience Asterisk 1.8 which MOR uses does not work properly with video over WebRTC.
