Hosted FreePBX Vultr - D65 TLS &SRTP Not Working

Found this out during a session with @defcomllc D phones won’t accept SSL Method Default and phones will fail with errors like EISSUER_MISMATCH EUNTRUSTED We set the SSL Method tlsv1_2 and phone provisioned nicely; S-phones did not complain about this change either. Updated https://wiki.freepbx.org/display/PHON/TLS+and+SRTP to reflect this change. May work with tlsv1_1 as well. Thanks for your help debugging this @defcomllc!

At least for D-series phones (and likely P-series ones) this will solve TLS issues.
