computer audio, only the Hold and Info soft keys are available. You can’t mute 
or remove a mobile phone or computer audio source.

Broadcasting Messages Using Push-to-Talk and Group 
Paging
The Group Paging and Push-to-Talk (PTT) features enable you to broadcast a 
message to as many people as have subscribed to a channel or have been 
placed in a group. Your system administrator can set up both features on your 
phone.
Group Paging mode enables you to broadcast a one-way announcement to 
people subscribed to a paging group. The people receiving the announcement 
can’t respond to the message.
PTT mode enables you to broadcast a message to people subscribed to a 
channel. The people receiving the message can respond to the message by 
broadcasting a message over the same channel. In this way, PTT is a 
collaborative broadcast mode.
Your system administrator can define up to 25 Paging Groups (for Group 
Paging mode) or Channels (for PTT mode). Your system administrator may 
assign a label to each group or channel that easily identifies the phones in the 
group or channel (for example, All, HR Dept, Shipping Staff, Executives, etc.). 
Each group or channel will have one of the following priorities:
Normal (for Groups/Channels 1-23)—Broadcasts sent to Groups/Channels 1 
to 23 are considered Normal broadcasts. When a phone receives more than one 
Normal broadcast, the first broadcast received is accepted, and all others are 
ignored (not played and not stored). By default, all phones receive broadcasts 
sent to Group/Channel 1.
Priority (for Group/Channel 24)—Broadcasts sent to Group/Channel 24 are 
considered Priority broadcasts. All phones receive Priority broadcasts unless 
Do Not Disturb is enabled. If a phone receives a Priority broadcast while an 
Emergency broadcast is already playing, the Priority broadcast is placed on 
hold. Phones play Priority broadcasts at the phone’s current audio level.
