AT&T 518-455-317 manual Using Telephones, Basic Call Handling Features

■A second call can ring at the system phone while the standard phone is busy, but do not use the system phone to answer the second call until the standard phone is idle or the first call will be disconnected.

■If you make a voice-signaled intercom call to a combination extension with a system phone, only the system phone signals.

■The lights on the system phone show what the standard phone is doing as well as what the system phone is doing. For an explanation of light patterns, see “Lights” at the beginning of this chapter.

■If Privacy is active at a combination extension, no other extension can join a call in progress at either a system phone or a standard device. (However, a phone can interrupt a call on a standard device at the same extension. For example, if a system phone and modem are combined at an extension, picking up the handset of the system phone could interrupt a modem transmission, even if Privacy is active.)

■While on a call on a standard phone, you can use the system phone’s dial-pad and fixed-feature buttons to handle calls. For example, you can use the system phone to select a specific outside line, and conduct the call on the standard phone. Or, if someone is on a call using the standard phone, someone else can put that call on hold by pressing

[ Hold ] on the system phone. To do this, it is not necessary to lift the handset of the system phone. Held calls do not ring back at a standard phone in a combination extension. To retrieve a held call from the standard phone, use Direct Line Pickup—Active Line.

■A standard phone’s message waiting light will not light if Background Music is playing through system phone’s speaker.

■If you have Caller ID, only the system phone can display the Caller ID information.

■The ringer equivalence number (REN) of a standard device or the combined REN of two devices cannot be greater than 2.0. (The REN of a system phone is 0.0.)
