And to answer your question, I think this:

1) If you have setup a SIP account with a proxy, then only your
connection to that proxy is secured (I might be wrong, choose TLS in
transportation). So also your partner must do it, else his/her
connection is not secured.

2) If you directly connect to someone else (his/her firewall port must
be open for this) then I think the whole conversation is secured. But I
might be wrong (as I'm no dev).

As I wrote, I'm no dev and I might be wrong.
