Kamailio scripts to call from websocket UA to classic UA, and vice versa.

I will write a blog entry explaining how this works, but in a nutshell:

• 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 (sometimes, it works)
• Tested with Chrome, FF, and Opera
• Remember to also change the record_route_preset() value
• I tested calls between:
  • jssip to csipsimple
  • csipsimple to jssip
  • csipsimple to csipsimple
