The telephone circuit in my home has two phone jacks:

Jack #1 serves a Panasonic KX-TG5210 5.8 GHz Cordless Phone and a hard-
wire AT&T Trimline phone.

Jack #2 serves a hard-wired AT&T Trimline phone.

When an incoming call arrives:

only one phone rings
or only two phones ring.
or the loudness of the ringing varies from phone to phone.

How do I get all phones to ring and to ring loudly?

Not enough information to provide a cogent answer. Is your home's
location urban, suburban, or rural? Is your telephone service provided
over copper wires, coaxial cable, fiber optic filament, or some other
medium. Is all of the telephone wiring in the home of the same age and
type?

My home is in the city of Riverside, California.
The phone service is via copper wires (about 35 years old).

Look at the bottom of each device for the REN, add all the
rens for line 1 and for line 2.
The phone office has a max REN load of 5.0, other sources
may lower, 3.0 or even 1.0 .

If you exceed the max allowed, some or all devices won't
ring or work. Disconnect a few to get under the max limit,
generally turning the ringer "off" does not change the load.

1 Ringer Equivalent Number is the equivalent load of the
standard single line 1960's desk telephone (model 500 or 2500).
