I am getting Vonage VOIP and don't want to run new phone wires. Since I need 2 phones, I need to get a 3-handset product. The first (main) unit will sit with the router and the other two (which must ONLY require wired power, NOT telephone lines, should communicate with the base over the air) units will be where they are needed. Phones must:
-
Be compatible with Vonage VOIP. I assume all phones that take a 2-wire telephone line should work, right?
-
Have good range.
-
Additional bases must be able to communicate over the air with the main base requiring no phone lines to be run to it.
-
Have wired headset option (usually a 2.5mm jack).
I found lots of units at the $40-$60 price range, but it doesn't say if they have the 2.5mm headset option.
Look at gigaset handsets. Not all of them support srtp and tls though.
Hurray for getting new phones and don’t let this post stop you from doing that.
..but if phone wire already exists at the locations you want phones, you could just disconnect the house/apartment/condo phone lines from the local phone companies POP (CPE, DEMARC, whatever box on the side of your house / apartment). Once you do that, connect the ATA (VoIP to analog converter) from Vonage to any jack in your house and all jacks will be live on that Vonage line.
If that sounds to complicated, a low voltage cabling company could do it for you in about 5 minutes and shouldn’t cost more than a service trip minimum which (depending on where you live) should be less than the cost of new phones.
To directly answer you question on cordless phones, I’ve always had decent results with Panasonic units. Anything in the KX-TG line will likely fit your needs.
Basically, I’m sick and tired of the snarly clutter of a wired headset on my desk (connects to an old-school cordless phone). I can’t find a gizmo for sale, so I’m going to figure out how to make one. This seems like a great introduction to Arduino, but I could use a little direction.
Can you help me start narrowing down which board to use?
It will have one purpose: connecting a mono BT headset to the analog jack. It’s a ten-year-old headset, so I don’t think I need much in the way of processing power, speed, etc. Even if I need a different headset, it’d be just voice calls w/o wind, noise cancelling, voice command, etc. I can even do functions like mute and redial on the phone itself. I just want to ditch the wire.
I’d like it if it were pocket-sized, but it doesn’t need to be tiny.
I think this points to the Uno or Nano, but not sure where to go from there or even if I’m heading in the right direction. And once I’ve narrowed down the board, then what? Am I correct that I need a breadboard too? And then shields (modules?) for BT and the analogue wire connectivity? Is adding a rechargeable battery easy enough or should I stick with a 9v?
Other than a case (I can 3D model/print that), is there anything major I’m overlooking hardware-wise?
