After some searching I was able to find someone who claims "The voice server connects only, as mentioned, 59437 - 59581 (the first time) and this goes through port 5222."

I also came across this URL containing all the whatsapp IPs: http://www.whatsapp.com/cidr.txt

If you still can't get this sorted out I can try emailing a contact I have at Whatsapp to see if he can provide further details.
