Re: Providers that can offer non-published phone numbers?

I wanted to provide a follow-up for everyone who helped me along in selecting the right provider and hardware.

My Obi100 came in and I also signed up for a Callcentric account with a new phone number for testing. I'll port my existing number later on, but I finally managed to get things working and made a test call and it sounds great. Of course I'm going to test it a little more in-depth this weekend, especially tweaking my firewall on exactly what traffic I want going to it.

This leads me to another question about the Obi100's activity. Since all my traffic routes through my firewall, I was monitoring what sort of stuff it was doing.

Now according to Callcentric's own web page here:

At the bottom they say to keep ports 5060-5080 open to Ok, no problem there. I also had to open up DNS so the device could do lookups...no biggie. Well here's the thing, I started seeing other hosts it was talking to. Maybe you can help me determine if this is legit or needs to be locked down. - Amazon. Why is it talking to Amazon? - Wireless Time Company. Ok, I can see the NTP usage here, but I specifically input time.nist.gov and saw no traffic going to that address. What's up here?
The moment the idea is admitted into society, that property is not as sacred as the laws of God, and that there is not a force of law and public justice to protect it, anarchy and tyranny commence. -John Adams, 1787
