Endeavor phones have “small displays” (see illustration, above) that cannot
show Caller ID and Name simultaneously, similarly to the MLS phone
displays.

Electrically compatible with the original MLS phones, these current-
manufacture system phones have a 2-line, 24-character display (18D and 34D
models) that has a pleasant adjustable back-lighted display with 3 display
angles. This is a rare feature in the industry.
Phone size numbering is non-intuitive: the -18 phone has 16
line/programmable buttons, plus two Intercom buttons, but the -18D has an
additional 4 programmable, non-lighted buttons.
In addition to the variable-counted buttons, all Partner phones have 8
common feature buttons and the 12 standard dial buttons.
Like the MLS phones, Partner phones have an adjunct jack for connection of
Tip/Ring devices such as a fax or headset. Unlike MLS, the Partner phones
are better built with a sturdy circuit board, and have low reported incidents of
failure.
