Problem was a garbled certificate chain. Browsers validate it fine,
because they have the needed root/chain certificates from vendors preinstalled. SIP phones/softphones don't.
Bottom line, TLS will work when the command
openssl verify -CAfile /etc/freeswitch/ssl/cafile.pem /etc/freeswitch/ssl/agent.pem
returns "agent.pem: OK".
Hope this helps someone.
Cheers,
