Polycom CX5000 System User’s Guide
 
 
Place a phone call 
When the Polycom CX5000 device is on-hook (the On/Off hook button   glows orange), 
you can use the LCD dial pad or external dial pad to enter the number, and then press the 
On/Off hook button to dial the call.  
When the device is off-hook (the On/Off hook button 
 glows green), the Polycom 
CX5000 device dials the call after you enter the last digit of the number.  
Answer an incoming phone call 
>>  To answer an incoming call, press the On/Off hook button  .  
Conference calls 
You can dial directly into a conference or, if necessary, dial into a conference bridge that 
facilitates telephone conferencing. 
If your conference requires connecting to a conference bridge, dial the conference bridge 
phone number on the Polycom CX5000 keypad using the on-hook or off-hook methods 
described previously. After connecting to the conference bridge, follow the prompts for 
entering the conference ID and password. At any time during the conference, you can 
suspend audio transmission using your Polycom CX5000 device.  
 
Three-way calls 
When you need to interrupt an existing conference call to call someone who, for example, 
might have an answer to a question or advice for a situation, you can place a three-way 
call. The conference call is temporarily suspended while you call the third party. You can 
choose to join the third party to the conference call, or you can end the call with the third 
party and rejoin the conference call.  
Note 
You must use a phone system that supports multiple phone lines to place 
conference calls.
