VoIP is not telephony.  VoIP is internet traffic.  In order to eavesdrop
on a SIP call (non-SRTP) all you need is packet sniffer and
(in)appropriate network access from someone who is on the route.  A VoIP
call is as secure as sending an e-mail.  Any device that you can imagine
for trolling the internet for keywords can easily be modified to troll
through VoIP calls as well.

I do not know of any VoIP providers that support secure RTP (SRTP)
connections (which would only secure connections to/from the provider).
Asterisk supports SRTP in the development version.  It should be
available in version 1.8.  I do not know about FreeSwitch.  Various SIP
phones support SRTP as well.  In the end, unless you trust/control both
endpoints of a call, your VoIP call is not going to be truly secure.
