Anyone use an old school intercom between house and garage?

Door bell?

Gee thanks.
FWIW, I use a RAM on my two wheels and mostly try to not use my cell phone when I'm awake. It's often left behind in my shop, work sites like sawmill or in the MULE glovebox. Not one of my prorities to be real honest but they are handy and great for travel and in the woods for safety.

I'm avoiding putting a cellphone mount on my bike, I just keep it in its holster. The holster almost cost me as much as the damn phone did.

Mines in an OTTER case which I've broken and glued up already...
Otter LT warranty doesn't apply to obsolete models like my S5...
