>From packet8's most recent 10K filing:
We developed the core software associated with the Virtual Office product line including the call control engine, protocol stacks and network address translation (NAT) traversal firmware for the customer premise equipment. As a result, we are able to update the software functionality of our services without third party assistance and limit the distribution of our unique customer premise equipment features such as NAT traversal to customer premise equipment that is sold in conjunction with our services.
There is no way they could do what they do if they limited themselves to configuring existing devices.

I wouldn't say it's trivial to do it, but one of our partners has a 100%
custom-written and RFC-compliant stack and softphone which goes to great
lengths to penetrate any NAT--they guarantee it. Licensing starts at
$42,000, however for a company the size of Packet 8 that would be trivial.
