1)I would like to have an extension # ring on three sets, at different locations in building? Is this possible? How?
2) if 1 not possible, can I have more than one speaker(loud bell) on same extension? Installer can't guarantee more than one speaker would work? If yes, how many (need three)?
3) any other solutions
