Throughout the SSCA® SIP training program there are examples of SIP trunking configurations.  To help us demonstrate these configurations, The SIP School has partnered with 3CX and you can download your free trial of their Phone System via this link and try it for yourself.

We'd like to thank the team at 3CX for all of their help and support and this is what their CEO has to say:

"3CX Phone System is based on the SIP standard and also has integrated WebRTC technology within its web conferencing feature. Therefore, it's the perfect solution to help educate people on the benefits and usability of SIP as well as WebRTC. We are very proud to be able to to help The SIP School do this by using 3CX Phone System during their courses and plan on continuing to do so."
