For vonage, can you use the same telphone as both the vonage phone and the traditional phone?

Question

or do you need a seperate phone for vonage and a seperate one for the traditional line?

I'm using a wireless router in addition to the voip router.

Answer 1

The default setup for Vonage (or any other VoIP provider) requires a dedicated telephone for VoIP service.  What you speak of is a neat concept; however, I am not aware of a device that provides the functionality you describe. Sorry.

Answer 2

Actually, it is possible to use 1 standard PSTN telephone with Vonage VoIP and PSTN landline.

There are 2 ways you can accomplish this.  

The fist is clumsy and not very practical, but do-able.  Just unplug your PSTN standard telephone from your Vonage line and plug it into your PSTN standard phone line.  It works the same on either line.  Switch back and forth.  But more practically is to just use two separate PSTN phones - one for Vonage line and one for PSTN landline.

or,

Use a 2-line telephone (corded or cordless).

I think this is what you are really asking for in the first place.

On a 2-line standard PSTN telephone, just connect line-1 to your standard PSTN (phone company service) line, and line-2 to your Vonage phone (ATA) adapter.

When you make a call, just select which line you want to call out on, or answer on.

And, of course this will work with any VoIP service that uses ATA phone adapters - not just with Vonage.

Panasonic has 2-line PSTN phones (corded and cordless).

Actually, I soon plan to do exactly what you are asking, but between two VoIP providers, rather than 1 VoIP and 1PSTN.

Currently, I use 1 VoIP adapter with 2-lines (Linksys PAP2T ATA).  Line-1 is subscribed to InPhonex and Line-2 is subscribed to CallCentric (links through my profile).  I have 1 cordless phone connected to VoIP line-1 and another cordless phone on VoIP line-2.  

I soon plan to buy a 2-Line Panasonic phone to join both VoIP lines to 1 telephone with 2-lines..... less hardware to mess with and very easy to switch between lines.... makes good sense.
