DURING AN ACTIVE CALL 

Mute 

This function allows you to mute the microphone of the active audio device during a call; 

you can not be heard by the other party. You can still hear all other parties while mute is 

enabled. 

To mute/resume the conversation: 

Press button during a conversation to mute the current call, the icon will be shown on the 

LCD, and the power indication LED will blink. Press again to get the microphone return to 

normal conversation. 

Call Hold 

This call function allows you to place an active call on hold. In this case your IP PBX might 

play a melody or message to the other party while waiting. Other calls can be received and 

made while having a call on hold. 

To hold/resume a call: 

1) Press the HOLD button to put your active call on hold. 

2) During the call, there will be a "dodo.." sound for each 30 second, suggesting that there is 

a current call in Hold state. 

3) If there is only one call on hold, press the HOLD button again to retrieve the call. 

4) If there is more than one call on hold, press the Up/Down button to highlight the call, then 

press the HOLD button again to retrieve the call. 

Note: 

When you are under the call hold status, putting down the handset, the conversation will go 

on over the speaker instead of hanging up the call.
