Question
Are there any other systems like at

There could be old wiring. What's problematical is the bureaucracy and
lack of leadership with respect to telecommunications.

The difficulties with the cellular and the cordless telephones are the
hospital equipment interference, telephone signal dropouts, telephone
signal garbling and telephone signal warbling.
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _

What can be done where cellular and cordless telephones do not work in
many areas of an old 1950's hospital building?...

There are no bedside telephones for patients unable to get out of bed
at Boston's old Shattuck Hospital that has repositioned itself as a
community medical center with 26 ambulatory care specialties and
geriatric acute rehabilitation services for traumatic injury, surgery,
a cardiac or neurological event, cancer and such.

It's a technical problem and a problematical bureaucracy!
