Don't be too scared. With one hour of usage per month you don't have to be too worried about call quality.

My usage is way down. Everyone has cell phones so we don't really too much on the VoIP phone. The teenagers don't call any more it's all texting now.

It's one option and a good one if you intend on using a typical PC. It's a CentOS distro with asterisk and lots of add-ons. It may be overkill for a simple phone line.

There are distros designed more for flash devices. I don't remember the names off hand.

Since low-power was a recent thread you could consider a Cisco (nee LinkSys, nee Sipura) ATA. You need a model with an FXS port (to connect to phones). Once your phone number has been ported to Unlimitel you would disconnect your home wiring from the telco and plug the FXS port into one of your wall outlets. Then connect an answering machine and you have a conventional phone service with call waiting and caller id.

If you want a voice menu to thwart marketing calls (call 886-4748 for an example) or offer more features like voice mail to email you could put asterisk on a home router using OpenWRT. That's a little tricky I suspect.

You are looking for an VoIP ATA (Analog Telephone Adapter) and you need one with an FXS port (to connect to a phone).

I picked up a Sipura 3??2 (or something like that) at a linux fest for $10 used. I suspect you could find a used on ebay. Sipura was bought by LinkSys which was bought by Cisco. Expect to pay about $100 new.


There is an asterisk user group in Toronto called TAUG with a low volume mailing list. It could help you out too.

The traps that you'll find is that when you are doing a heavy upload or download voice quality may suffer. If you are uploading the remote caller will have trouble hearing your voice. On download it will be hard to hear them. Stop the download and it goes back to normal.

This can be overcome by using traffic shaping on your firewall and on the ISP service. Don't expect many ISPs to offer VoIP traffic shaping though. Unlimitel does and I imagine Packetworks may.
