AT&T 4.1 Telephone User Manual


 
Limitations
Because standard phones do not have line buttons or dedicated function
buttons, basic call handling procedures are sometimes different from those on
system phones. In addition, the following limitations apply to a standard phone:
You cannot change option settings.
Because there are no line buttons, users cannot manually select a line.
You can make outside calls only on automatically selected lines (for
information on Automatic Line Selection, see
Chapter 5).
If a standard phone is in use, there is no indication of a second call and
inside callers will hear a busy tone.
You can make a voice-signaled intercom call from a standard phone, but
if users try to make a voice-signaled call to a standard phone, it will ring.
Users cannot access the Conference Drop or Privacy features; however,
Automatic Extension Privacy (#304) can be Assigned.
Users cannot receive a group page.
Rotary phones cannot access any features that require dialing a * or #.
Touch-tone phones are recommended.
Only one outside call at a time can be dialed from a standard device for
each 206 or 200 module in the system. This means that if there is only
one 206 module and two users at standard devices want to dial outside
calls at the same time, one user must wait until the other user is finished
dialing.
Feature Phones
A feature phone is a standard telephone that has feature buttons in addition to
the regular 12-key dial pad. For example, there are feature phones that have
auto dial buttons, last number redial buttons, hold buttons, and built-in
speakers. You can use most of these phones with the system; however, there
are some limitations to what these phones can do.
The capabilities of a feature phone are in the phone itself. For example, if you
store a number on a feature phone’s auto dial button, that number is stored in
the feature phone. (This is different from storing a number on a system phone’s
Auto Dial button; in this case, the number is actually stored in the system
modules.) Similarly, when you press a Hold button on a feature phone, the call
is held at the phone itself. (Callers will not hear the system’s music-on-hold.)
Other phones in the system cannot see that the call is on hold (it appears as a
busy line).
If you want to store an outside number on a feature phone’s auto dial button, you
must add a 9 and one or more pauses (if available) before each outside
number. (The 9 gets an outside line, and each pause allows a few seconds to
get an outside dial tone.)
Note that the feature phone’s last number redial button may not work for an
outside call. To redial the last number, use the system’s Last Number Redial
feature by pressing [
#
] [
0
] [
5
].
