Offhook Voice Announce
Description
You can interrupt a busy extension when making an Intercom Call, and then use the Off-Hook Voice 
Announce (OHVA) feature to make an announcement that only the called party can hear. You can also 
transfer a held call to a busy extension after making the announcement using this feature. The called 
party may optionally reply to (answer) an OHVA call.
The busy party can reply to an offhook announcement with a text message that displays on the 
announcing phone. Any one of the following messages can be selected. Messages 6 to 9 and 0 have no 
default message text. All the messages can be changed through system programming. (see “Set Text 
Message Replies” on page 4-37 for more information on setting Text Message Replies).
Prior to the release of Version 2.7, it was not possible for a caller to activate the OHVA feature when a 
call was placed to an available second or third Directory Number (DN) key. Beginning with Version 
2.7, the calling party can activate the OHVA feature even when the second and/or third DN key is 
available. Depending on how this feature has been programmed, the calling party hears one of three 
different tones. Ring-Back Tone or Special Tone is heard when a call is placed to a “non-Voice Mail 
assigned” extension. When a call is placed to a “Voice Mail assigned” number, Ring-Back Tone or 
Busy Tone may be heard. Text Message Replies
