Query: GREAT Phone system...

Especially with the new voice over internet telephone systems such as callvantage or vonage! Priceless...esp...to update an old house and have phones in every room still just by plugging it into a wall outlet!!! only wish that you didn't have to reinput all the phone numbers to the memory of each phone (wish they were stored in the base unit somehow) but this is the only thing so far...and that also allows for one with work #'s etc...Overall great phone/system!
