Comments on: Vonage says Clearwire interfered with VoIP calls

As competition heats up Net-phone providers and traditional telecoms, blocked calls are becoming common.

It will take the FCC

To put its foot down and stop these M$ like tactics of anti competition.

So Why Don't They Just Use Common Ports?

Skype is flexible enough to use just 2 ports, like 80 and 443. What is wrong with Vonage? They require a huge block of ports to be open. Sounds like bad engineering. If these guys aren't savvy enough to travel under the radar, they won't stay in business for long, it's a jungle out there. Legal remedies always come to late to be of any help.

Vonage:
"You may need to direct certain ports to be accessible to our communications network in order to complete high quality phone calls. Each router manufacturer has a different process for Port Forwarding (also called Port Opening), but in each case, you must always specify two port ranges to be opened:

* 5060 ? 5061 (UDP)
* 10000 ? 20000 (UDP)"

Skype:
"Skype Technical FAQ
I can?t connect to Skype from work or due to a restrictive firewall. Which ports need to be opened in order to use Skype? The minimum requirement is that Skype needs unrestricted outgoing TCP access to all destination ports above 1024 (OR) to ports 80 and 443 (the former is better, however)."

I would cancel my ISP an go with another broadband provider if they did this to me.
