Just wondering is there a cordless phone set out there, which you can call other handhelds without connecting to an actual landline?
Got this Uniden XDECT 7055 from the old office https://uniden.com.au/wp-content/uploads/XDECT_7055_2.pdf, but it doesn't seem to ring other handheld station. You could however still hear the voice from other station when you select a particular number of a handheld station. Basically, just want like a walkie talkie setup. TIA
