About us

Vocale Ltd is the parent company of The SIP School and WebRTC School.

We pride ourselves on our ability to provide first-class education on SIP, VoIP and WebRTC along with industry-recognized Certifications.  Our main objectives are to teach not only the theory and practice of these subjects but to help students gain a greater confidence so that as these protocols evolve students are not afraid to work with new functionality.

When it comes to other companies that manufacture SIP/VoIP/WebRTC enabled equipment and provide services utilizing these technologies, then Vocale Ltd stands firm in its ‘no favorite’ policy as all of these companies are favorites.  If you are working with SIP/VoIP/WebRTC then we are positive that by working with Vocale Ltd you can help your staff develop their knowledge to be better able to support your own clients with your own products and services.  In fact, a lot of companies use our training to complement their own ‘product-specific’ courses.
