Such a feature probably would be useful to allow tunneling of SIP
through a HTTP(S) Proxy
1. client setup a tcp connection with HTTP proxy
2. client/HTTP-proxy talk something under non ssl stage (CONNECT)
3. HTTP proxy establish TCP connection to SIP proxy
and becomes "transparent"
4. start ssl negotiation between client and SIP proxy
