Feature Guide 95
1.7.4.3 Off-Hook Call Announcement (OHCA)
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 only when the called extension uses one of the following
telephones:
• If the KX-T7235G/FR/SL/NE are connected to the PBX, the OHCA feature for the
KX-T7235 should be disabled through system programming.
• The OHCA feature cannot be used in the following cases:
The Call Waiting tone is sent to the called extension. ( 1.7.4.2 Call Waiting Tone)
• If an extension user makes an OHCA call while the called extension has placed an
intercom call on hold, the calling extension will hear a ringback tone and the INTERCOM
button on the called extension will flash to show another call is waiting.
• While an extension is receiving the OHCA, if the extension user places the current trunk
call on hold or transfers the current intercom call or trunk call, the OHCA will become
disabled and the calling extension will start to hear a ringback tone.
• While an extension is receiving the OHCA, if the extension user places the current
intercom call on hold, the called extension can talk to the calling extension through the
handset.
