I got my installation kit for voice over IP for my home phone last night. It's pretty awesome. My home phone number doesn't get switched over until Friday, so I can only make out-going calls. All incoming calls still go through the old system.
The hardware they sent is just a D-Link 1120M that's specialized for the service. It's basically a single-port NAT firewall that you put between your cable/DSL-modem and the rest of your LAN infrastructure. If you're serving external service like a web site (like this one) then you have to delve into the configuration (which sucks compared to my Linksys router) to allow incoming traffic to successfully traverse the “double-NAT”. If the D-link had a DMZ option, it would be perfect, but it doesn't, so you have to forward ports on both routers. I plugged in an old phone and made a couple of calls last night, and there was absolutely no perceivable difference in operation between it and a regular phone line. Not thinking, I rebooted the router while I was talking to my dad, which of course ended our conversation. That was pretty funny. It just completely slipped my mind that I was not on a regular phone line.
The service lets you do awesome stuff like:
- Unlimited long-distance
- Have your voice mail sent to you in an email, or check it via the web, or send alert emails to let you know you have voice mail
- Forward your calls to multiple locations and have them ring all at once, or in sequence
- Schedule “do not disturb time“ when your phone will not ring (with an exception process for emergencies)
- plus lots more I can't think of
And it costs much less than we've been paying for our home phone service. This is starting to sound like a commercial, but I'm just excited about it. If you're paying more than $40 for your home phone service, let me know and I'll send you a referral so we can both reap the rewards.
