Speaker phone problem
It is possible. I have ATT 945(?) 4 line phones that communicate via a DSL-like signal between units to do special things like intercom, etc.
What I have in my setup is that I have a seperate line from the point of entry of my phone line to my DSL modem.
I then have TWO stacked DSL filters PER LINE that feed the main phone line running to all the phones.
Be AWARE that when using the speaker phone there is a modulation of the gains both directions. When you talk OR have a noisy background noise, the gain of the speaker is cut down to prevent feedback. And when you go silent, the speaker gain is increased for you to hear the other side of the call. Essentially it takes as much discipline as the old two-way radios... one talker at a time with these speaker phones AND very little background noise.
