SIP Training for Professionals

I have created this training for technical people working on Communication Service Providers and Contact Centers and VoIP Developers. The main bennefit for students is to improve job performance nd get better opportunites in the industry. For company owners this training can improve the quality of the technical support, retention of technical people and customer satisfaction.

This SIP course was updated in 04/2021 and includes:

  • 6+ hours on-demand video
  • 8 articles
  • 19 downloadable resources
  • Full lifetime access
  • Access on mobile and TV
  • Labs
  • Certificate of completion

The SIP training was created for the IT staff of mobile/telecom providers, ITSPs (Internet Telephony Service Providers), Consultants, Call Centers or any other company using IP telephony. The performance of these professionals is essential to reduce the churn and the stress of the operation. SIP troubleshooting is a key skill in these scenarios.

It is a result of years in the frontline of the tech support of a softs-switch developer, troubleshooting hundreds of deployments.

I have prepared two FREE gifts for this training. The first is a Virtual Machine in open virtualization format with a SIP server running as a Proxy, B2BUA and Redirect. The second is a list of SIP responses with comments on how to troubleshoot the most common SIP error messages. I sincerely hope you enjoy this training.

There are 5 practical labs to do with your VM and softphones in this training.
