Assuming underlying OpenSSL support, FreeSWITCH should support at least the following SSL/TLS protocols on the same profile and socket automagically (like Apache):

SSL v2.3 (shame on you!)
TLS v1
TLS v1.1
TLS v1.2

Comment by Brian West [ 02/Oct/13 ]
Tested with setting the method to sslv23 on the profile does indeed support them all.

<16>:java -jar TestSSLServer.jar 5066
Supported versions: SSLv3 TLSv1.0 TLSv1.1 TLSv1.2
Deflate compression: no
Supported cipher suites (ORDER IS NOT SIGNIFICANT):
  (TLSv1.0: idem)
  (TLSv1.1: idem)
Server certificate(s):
  48dec9e21d1036bc201f0b9c709fbc349616aac0: O=bkw.org, CN=pbx.bkw.org
Minimal encryption strength: strong encryption (96-bit or more)
Achievable encryption strength: strong encryption (96-bit or more)
BEAST status: vulnerable
CRIME status: protected

Extend it. To specify protocols and possibly ciphers.
Comment by Kristian Kielhofner [ 02/Oct/13 ]
Awesome. What about only supporting > version and up automatically. Config=tlsv1:

tlsv1 supported
tlsv1.1 supported
tlsv1.2 supported

ssl v2.3 NOT supported
ssl v3 NOT supported
Comment by Travis Cross [ 05/Feb/14 ]
Talked with Brian. The current state is clearly a bit awkward. The way forward is likely to be listing the versions you want to support individually. We're looking into this.
Comment by Travis Cross [ 06/Feb/14 ]
This is now in tree; please test. You can specify one or more protocols to support, e.g.

  <param name="tls-version" value="tlsv1,tlsv1.2"/>
