    Secured 3CX over public networks

    Windows only? I use MacOS and iOS. What about it? And what about sRTP? TLS is used only for signalisation. But the voice transmission also must be encrypted.

    Secured 3CX over public networks

    Could some explain how to get working 3CX clients with TLS and sRTP? I tried to use LE certificate for TLS on the server side and there is no any problem with Phonerlite softphone or Cisco SPA, they are connected without any problems. But 3CX clients shows me "TLS error". And it seems "RTP...

    Solved iOS-client problems

    I made some tests and it seems the problem is not in iOS clients. As I see the problem with the implementation of sRTP (RTP mode secure only) itself. It didn't work with desktop clients too.

    Solved iOS-client problems

    UDP ports from 9000 to 9500 are forwarded. With the normal RTP mode it seems to be working but I need encrypted calls on public networks.

    3CX Tunnel

    OK. Could you explain how TLS works in your 3CX clients? I install LE certificates on the server on port 5061, check it with openssl s_client and Phonerlite softphone and it works fine. But your client won't connect. As I understand if I use 3CX Tunnel the connection established from localhost...

    Solved iOS-client problems

    Already tried more than 20 times. UPD: Interested fact. When I try to call from one iOS-client extension to another desktop-client extension (there is no any more clients connected) there is no any ringer on desktop but I see "In a call" status or caller. And when I close iOS client and put...

    3CX Tunnel

    But as I understand only 3CX Client can use SRTP, isn't it?

    3CX Tunnel

    So as I understand the only way to get encrypted connection with encrypted voice is to use 3CX Client without 3CX Tunnel and use TLS with RTP Mode = Only secure? What about IP-phones? Other softphones?
