The Off-Hook Voice Announce (OHVA) feature allows an intercom caller (either single line 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 party can then talk freely on both connections, using the handset for the original call and the speakerphone for the OHVA intercom call. 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.
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 endpoints can be programmed for placing OHVA calls, as necessary. Inter-Tel endpoints without PC Data Port Modules or sec- ondary voice paths, and single line endpoints cannot receive OHVA calls since they do not have secondary voice path circuitry. By default, OHVA is disabled at the station level.
• Mini-DSS-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 DB Program- ming. 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.
If you press the button while speaking to an OVHA 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.
To place an OVHA call:
1. When placing an intercom call to a busy OHVA-enabled Inter-Tel endpoint, do not hang up. You hear busy sig- nals until the Camp On and O H VA S c r e e n i n g t i m e r s expire. If you hear music after the Camp On timer expires, conditions for an OHVA call were not met and you are camped-on. See page 166.)
2. When the OHVA Screening
timer expires—and if the endpoint’s secondary voice path is available—you are auto- matically connected to the called party’s speakerphone.
To place an immediate off-hook voice announce call (Inter-Tel endpoints with Mini-DSS buttons only):
This method can be used only if the database has been programmed to allow Inter-Tel end- points with Mini-DSS buttons to bypass the Camp On and OHVA Screening timers.
1. When an intercom call is placed, using a Mini-DSS button, to a busy OHVA-enabled Inter-Tel endpoint, do not hang up.
2. Press the Mini-DSS button for that endpoint again. If the endpoint’s secondary voice path is available, you are immediately connected and may speak.
To receive an OHVA call (OHVA-enabled Inter-Tel endpoints only):
1. While on a call using the handset, you hear a camp-on tone. The display shows CALL ANNOUNCE FROM <username>. Do nothing. When the OHVA Screening timer expires, you hear a double tone. You are connected with the intercom caller via the speakerphone. Your original call remains connected on the handset.
The system provides the following language options: American English, British English, Span- ish, and Japanese prompts and displays. Administrators must know which languages are consid- ered Primary and Secondary for the system.
If you press while speaking to the caller on the speakerphone, the handset microphone will be muted and the caller on the handset will not hear you or the OHVA caller. Press again to enable the handset.
IMPORTANT
To place an OHVA call using a single line endpoint, the Ring Intercom Always feature must be disabled. To disable this feature, lift the handset of the sin- gle line endpoint and dial feature code 377. By default, the Ring Intercom Always feature is enabled.

2. To terminate the OHVA call: Press the lit Speaker button or have the OHVA caller hang up. If you terminate the original call by hanging up the handset, you remain con- nected to the OHVA call in the handsfree intercom mode.
To block an off-hook voice announce call (OHVA-enabled Inter-Tel endpoints only): 1. While on a call using the handset, you hear a camp-on tone. The display shows CALL
ANNOUNCE FROM <username>. To cause the intercom call to camp on, press the Speaker button. The button flashes.
2. If you want to send Do-Not-Disturb signals to the camped-on call, press the
button.
