Hey guys,
Just wanted to report that I finally got around to mounting my DS7000 in a hidden place, where I added a phone jack, which is powered by my VoIP service.
Essentially, what I've done, is disconnect my phone line from the POTS box outside my house. Then, I added a jack next to my VoIP adapter (hidden in a closet and powered by a UPS), which connects to the "phone" port of my adapter. At that point, all my phone lines around the house got a dial signal without a problem. I now have two phones plugged in (master bedroom and downstairs kitchen), which work w/out a problem.
Because I also wanted the DS7000 hidden away, the new jack is simply connected to the same phone line that connects to my VoIP adapter.
Just over the weekend, I tested the DS7000 by programming my cell number on it. I tripped the system and sure enough, the DS7000 called me and I was able to listen in by pressing 0. The DS7000's mic is very sensitive. You can hear just about everything around the house (even from w/in the closet.)
For the record, I'm in the process of switching VoIP providers, so I currently have two VoIP adapters to play with. I tested both and they work w/out a problem!
So, in short, VoIP does work, but I think it depends on a number of things:
* Your adapter should have the latest firmware to ensure QoS and the right protocol support. One of my providers (the one I'm leaving) has a locked adapter (SPA-2100), so I had to call them multiple times to get them to update the firmware. The other (SPA-2102) is unlocked, but it required that I call my provider to get the admin password. Then, I updated the firmware to the latest version, which I d/l from Linksys
* the VoIP adapter should be directly connected to the cable modem. Of course, for that to happen, the adapter must also be a router, which both of mine are
* although my new provider does allow me to turn on/off "fax mode", I haven't had to do it to get the DS7000 to dial out, so it's not true that you need Fax support for your line to work properly
I hope this helps..
