FreeSwitch as Media Server and SBC for Kamailio 3.1

There is a new version of step by step tutorial about using FreeSWITCH and Kamailio together for large VoIP platforms.

Besides upgrade to use latest Kamailio major stable release, v3.1.0, there are couple of new features added in the architecture of the VoIP platform:

  • along with providing media services (voicemail, conferencing, a.s.o.), FreeSwitch is used now also as SBC for topology hiding and media relay (this helps for transconding needs, playing audio messages during the early session or NAT traversal)
  • Kamailio config has added features to detect DoS/DDoS and scanning attacks, secure SIP communication over TLS, IP authentication and a bunch of neat things that help for an easier maintenance and update of parameters such as database connectivity details, local IPs, etc.
