MANUAL SIGNALLING
Use this feature when you want to send a brief 500ms ring burst to another
station, regardless of the status of your phone (on-hook, off-hook, handsfree,
DND or ringing).

nated station.
NOTE: Your phone must have a Manual Signalling (
MSMS

number extender assigned to it.
OFF-HOOK VOICE ANNOUNCE
Keysets may receive a voice announcement while on another call. The calling
station must have an OHVA key. When you are in DND, you cannot receive
OHVA calls. The OHVA feature will work with intercom calls and transferred
calls.
To make an off-hook voice announcement:
• Dial the extension number or press the DSS key.
• When you receive a busy signal, press the OHVA key.
• After the attention tone, begin speaking.
• Finish the call by replacing the handset or pressing the ANS/RLS or the
MONITOR key if you are using a 7B phone.
NOTES:
1. When you are voice announcing to a station close to you, use the handset to
avoid an echo effect.
2. You cannot off-hook voice announce to single line telephones.
When you receive an off-hook voice announcement, if you are using the hand-
set, you will hear the announcement over the handset receiver. If you are using
the speakerphone, you will hear the announcement over the keyset speaker. In
both cases, you can continue to speak to the original party.
• Press the flashing CALL button on your keyset. This will place the original
party on hold and allow you to talk to the announcing party.
• To return to your first party, press the key corresponding to your original call.
This will disconnect the OHVA call.
Executive off-hook voice announce allows you to engage in conversation on
your keyset and simultaneously receive and reply handsfree to an OHVA through
your add-on module (AOM). Use caution because the conversation through the
AOM may possibly be heard by the caller on the keyset. When you receive an
executive OHVA through your AOM:
