SIP differ in a lot points from FTP:
- it uses normaly UDP not TCP (although TCP is possible according to the
newset RFC3261)
- it needs more then one related connection (ok thats not a problem any more)
- its a ASCII based protocol related with http
- it can contain hostnames instead of IP <- and thats the reason why it exist
no conntrack helper and i do/will not write such a module
