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 126.96.36.199/24. 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.
188.8.131.52 - Amazon. Why is it talking to Amazon?
184.108.40.206 - 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?
