You can place a phone call on hold directly from Rainbow. Placing a call on hold will isolate your caller. You will not be able to hear or talk to them until the call is reactivated. 
The telephony functions are only available from your personal computer.

NOTE:
This function requires a PABX connection.  Please contact your company's administrator for more information about this.
