WebRTC with Kamailio

I noticed lots of queries about this subject, and I created a Kamailio sample script that could help those who are in trouble when working on this.

This post is planned to be explanatory, with some level of detail, but I don’t really have time nowadays so I’m gonna throw it in its current state, hoping to find the time to do it properly soon enough.

• This script is configured to run behind NAT, port TCP 10080 and TCP/UDP 5090 are exposed to the Internet
• You have to create valid users using, preferably, “kamctl add …”
• RTP ports should be open in range 30k-35k, inclusive
• I used jssip as webrtc SIP UA: http://tryit.jssip.net/
• Always disable video before placing a call from jssip UA
• Always use Chrome. Firefox won’t work, and I’m not sure about other browsers
• I tested calls between:
  • jssip to csipsimple
  • csipsimple to jssip
  • csipsimple to csipsimple

This is the link to the script
