Partner has excelled at single-line telephone support from the beginning,
allowing users to attach a standard tip-ring phone to any system port, or as an
adjunct to any system phone.
Since the introduction of Caller ID support, system phones have been able to
display Caller ID information, but unfortunately, Caller ID is not passed
along to attached standard telephones.
Partner supports Message Waiting indicators on single-line phones with low-
voltage LED lights. The older neon-based message-waiting indicators do not
work.

When a system phone and single-line phone are combined at one
extension, both message waiting lights will function.

Neon-based MW lights require 90 volts AC, similar to ringing current.
