Integration guide for Asterisk based systems

Setup Websocket for Asterisk PBX (SIP / PJSIP stack)

1. Upload a valid certificate to the server (not self signed)
2. Setup /etc/asterisk/http.conf with the following:
   [general]
   enabled=no ; disable HTTP
   tlsenable=yes
   tlsbindaddr=0.0.0.0:8089
   tlscertfile=/etc/ssl/certs/my.cert.pem
   
3. When using SIP stack
   Setup /etc/asterisk/sip.conf with the following:
   websocket_enabled=yes

When using PJSIP stack
Setup /etc/asterisk/sip.conf with the following:
websocket_enabled=no

4. Add to /etc/asterisk/rtp.conf
   stunaddr=stun.l.google.com:19302
   icesupport=true
   If behind NAT also add the private IP and public IP.
   [ice_host_candidates]
   192.168.1.100=> 12.12.12.12
   
5. Restart asterisk
6. Check websocket service in asterisk with the command:
   asterisk -rx ‘http show status’
   If you see the following, you are good and able to place and receive calls using a websocket connection.
   Please take in mind to also adjust the firewall so that inbound traffic over ports 8089 is allowed and forwarded to you asterisk machine.
