7.2 Placing Calls On Hold
You can place a call on hold in order to answer an incoming call (see Section 7.1 ) or to make
another call. The party put on hold will hear music played (Music on Hold (MOH)).
 To place a call on hold:

Accept an incoming call and then press the HOLD hard key.

To retrieve a call on hold:

Press the HOLD hard key again or touch the Resume softkey.
Note: When using the handset in a call, if the handset is on-hooked after putting the call on
hold, the call is not disconnected and the audio is switched to the speaker . For the call to be
disconnected
, as it was in earlier versions, refer to your network administrator.
7.3 Handling Multiple Incoming Calls
The phone is capable of handling up to eight concurrent calls per line. Multiple calls can be put on
hold and you can switch between them. This feature is valuable for front desk personnel.
 To manage multiple incoming calls:

If a call comes in from Steve and then after it, a call comes in from Donald, when you answer
Donald, Steve is put on hold.

If a third call comes in, this one from Hilary, and you answer it, Donald is also put on hold, so
now both Steve (caller 1) and Donald (caller 2) are on hold.

To toggle between callers:

Press the upper or lower rim of the control button to navigate from one caller to another or
just touch the caller's name in the screen.
