Have existing 30 yr old Music & Sound wired intercom system that supports doorbell & radio. Thinking about retiring it since we'll have to add support for new section of house. Looking for recommendations for intercom
- doorbell that uses standard wired phones. Don't think I'm interested in video. Have googled a little and found hits at quantrometrics & futurehomesystems among hundreds of others. Anyone have some real-life feedback with this type of product?
