OFF-HOOK VOICE ANNOUNCE (OHVA)
The Off-Hook Voice Announce (OHVA) feature allows an intercom caller (either single-line
set or Inter-Tel endpoint) to establish voice contact with the called Inter-Tel endpoint user, even
though the user already has a call in progress on the handset. The called endpoint user can then
talk freely on both connections, using the handset for the original call and the speakerphone for
the OHVA intercom call. Note that the caller on the handset call
will be able to hear the OHVA
call.
In a network, intercom callers can establish OHVA calls to Inter-Tel endpoints on other nodes.
A PC Data Port Module (PCDPM) must be installed on a digital display endpoint to provide
the secondary voice path needed for the OHVA feature. The analog endpoints and Executone
IDS endpoints do not require any additional equipment.
NOTE:
IP and SIP endpoints do not support OHVA.
To enable the OHVA, the following must be completed:
•
The OHVA system flag must be enabled. (When the system is in the default state, this
flag is enabled.)
•
Each OHVA-equipped Inter-Tel endpoint can be programmed for placing and/or receiv-
ing OHVA calls. (By default, OHVA is disabled at the station level.)
•
Other Inter-Tel endpoints and single-line sets can be programmed for placing OHVA
calls, as desired. Inter-Tel endpoints without PC Data Port Modules or secondary voice
paths, and single-line sets cannot receive OHVA calls since they do not have secondary
voice path circuitry. (By default, OHVA is disabled at the station level.)
•
DSS/BLF-equipped digital display endpoints can be programmed to override the Camp-
On and OHVA Screening timers and make “immediate” OHVA calls. This is a useful
option for Attendant stations.
Any combination of OHVA-enabled and -disabled stations is available through database pro-
gramming. For example, all Attendants may be programmed to make, but not receive, OHVA
calls, while other stations are allowed to receive, but not place, OHVA calls.
OHVA calls cannot be processed if the secondary voice path or the speakerphone of the called
endpoint is not available. This occurs when the endpoint has a different OHVA call in progress,
has an active data call in progress, is on an active handsfree intercom or outside call, has
handsfree disabled, has a call being changed from handset to speakerphone, has a headset
enabled, or is in Do-Not-Disturb. Also, OHVA calls are not possible if the caller is placing a
private intercom call or has the Ring Intercom Always feature enabled.
NOTE:
To place an OHVA call using a single-line set, the Ring Intercom Always feature must
be disabled. To disable this feature, lift the handset and dial 377 (Ring Intercom Always ON/
OFF feature code) on the single-line set. By default, this is enabled.
If you press the button while speaking to an off-hook voice announce caller on the
speakerphone, the handset microphone will be muted and the caller on the handset will not
hear you or the OHVA caller. When you press
again, the handset microphone is re-
enabled.
