I've successfully used TLS with FreeSWITCH at both ends (yes, that's with
FreeSWITCH itself as the softphone).

Snom 320 phones are known to work as well if you set up SRV records for the
TLS.

I haven't tried other softphones because, basically, FreeSWITCH is a better
phone than anything else I can find.

To debug this, try wireshark or tshark to find out whether your softphone is
trying to connect over the TLS port at all.
