I have a two line digital phone at home and I conduct much business at home. I cannnot seem to find a two line digital phone system. It seems the top pick is panasonic but the newer models are only one line. Any suggestions on a two line phone system? I might just go to one line and use my cell phone more at home as it appears we now have better cell access.
