RE: SIP-T20P: Register Failedand and no Call
Dear Daniel , I have already connected 12 phones here. Thanks again. The information I have written are wrong. We have 3 branchs in another cities and need to connect many phones there accessing this network here. My only option is the Internet.
But I am confused on how to use STUN server and client. (http://www.3cx.com/pbx/what-is-a-stun-server/).
If you can point me to any tutorial to do this. Need a program? Where can I download? 3CX have?

Thank you for your attention.

Sylvio
