Unsupported 3CXPhone 6 - TLS

[TheCourierr]

Hey i try to connect my 3CXPhone 6 softphone to a freeswitch sip server on TLS.

I cant get it to connect even when i import the certificate. What version of TLS the softphone uses? if its below TLS 1.2 or even SSL that would explain it.

That is a very old, unsupported and discontinued app and we never provided support on it for 3rd party servers.

You might want to use a different softphone in this case.
