I read it all and my only though was: use a VPN.

If someone wants to stop SIP, it has an easy to spot pattern. 
If someone wants to stop VPN, they will drop every non clear connection which 
doesn't match a known non-VPN pattern.

If I was afraid of my telco listening in on my SIP dialogs, I'd also want to 
encrypt RTP. Which is much more resource intensive than encrypting a few SIP 
messages. So if you think standard tls is to intensive you'll also have to 
create some custom lightweight rtp mangling.
