The Call Waiting Screen - ZyXEL Communications X6004 User Manual

21.8 The Call Waiting Screen

Call waiting allows you to put a present call on hold and answer a new call. When a second
call comes in, the X6004 sends a beep tone to you. You can decide to ignore it or to switch to
the second call using one of the following methods.
• press the flash button on your telephone
• very quickly press and release the on-hook switch on your telephone
You can switch back to the first call using the same methods above. When you hang up one
call, the X6004 sends you a ring tone if another call is still waiting.
This feature only applies to extension receivers which use SIP or analog
phones.
The following figure shows how call waiting works.
