OpenSIPS advanced training

@ Cluecon 2016

Using all the tools in the OpenSIPS ecosystem to improve, expand and monitor your FreeSWITCH installations and Telephony platforms


The concept of this training course is to spend the day building from the ground up a fully operational VoIP system around OpenSIPS and FreeSWITCH:

  • Using OpenSIPS as the front end for scaling your FreeSWITCH PBX
  • Load balancing inbound traffic to the cluster of FreeSWITCH servers
  • Registration decoupling, protocol conversion and traffic sanitization
  • Routing traffic via OpenSIPS for LCR, Fraud detection and Security
  • Realtime traffic capturing and monitoring with Homer
  • Implementing CGRates as the billing engine for your platform

Training Attendees will be provided with virtual machines/containers to follow along and get a hands on experience building the final functional product, plus access to a video library of “OpenSIPS basics” prior the event study fundamentals or brush up on their knowledge

An official OpenSIPS "Certificate of Attendance" will be provided for succesfully completing the OpenSIPS and FreeSWITCH integration training.

From start to finish, each phase will be lead by a different instructor who specializes in that particular component. The idea being that the same system used in the first phase will be built upon during the ones that follow.
