Second request.
In the 1980s, "ringing out" with a portable house phone, also known as a cordless phone, involved a process similar to using a traditional landline phone, but with the added convenience of mobility within a limited range of a base station. The base station would connect to the public telephone network, and the handset would communicate with the base station via radio frequency. When a call was placed, the base station would transmit the ringing signal to the handset, which would then alert the user with a ringing tone.
So long as you was within distance of the base station within the house you could ring anywhere. I had one, I could sit in the garden and answer calls and I could also ring out. If I went down the street and lost contact with the base station (charging point) inside the house I couldn’t ring anywhere or answer a call, Why do you think they had numbers buttons on the phone if you couldn’t call anyone.
