Description
An extension user can talk with a busy extension through the built-in speaker and microphone of the called
party's PT. If the existing call is using a handset, a second conversation is made using the speakerphone and
microphone so that the called extension can talk to both parties.
Conditions
•
COS programming determines which extensions can use this feature.
•
This feature is available when the called extension uses one of the following telephones:
–
KX-T7625, KX-T7630, KX-T7633, KX-T7636, KX-DT333, KX-DT343, KX-DT346, KX-DT521,
