Humm, no reply so far, may be because my email was
very long and no body
bothered to read it all. Anyways, here is the shorter more direct version
of it.
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.
