If I call an extension and they don't answer how do I program the phone so that I can leave that person a message? I'm using Panasonic KX-T7453 Thanks Chris

Start by dialing 500 on the intercom. If that gets you into the voice mail system, then you can dial *710x 500 # where x is 4 for No Answer and 5 is Busy/No Answer call forwarding. The number of rings before the forward is controlled by *713yy where yy is a time in seconds. Each ring cycle is about 6 seconds, so 24 would be a good number.

Leaving a message on your own phone? Dialing 500 gets you into your personal mailbox as an owner. Dialing #8 and your extension gets you into the VM system as a caller. (or it might be #6, I don't have my VM online today)

Of course, if you have an ESVM instead of the TVx system, then the procedure is entirely different.

Here are some other features you may need

Make sure your Auto Answer button is lit up, so you can receive intercom announcements, and respond hands-free.

Use the Call Forwarding (FWD) to send un-answered calls to another phone or to voicemail

Press BGM (or 1 on the touch-tone pad) for background music, if your system is equipped.

Use Absent Messages to show text messages on other people's phones when you are away.

Use System Call Waiting so your phone will ring even when you're on the phone. Press Intercom and dial 7311 to set it up, or 7310 to cancel.

Use Do Not Disturb (DND) when you don't want to receive calls. Press Intercom, press FWD/DND and dial 1 to activate, or 0 to cancel.

Press MESSAGE when you call a busy intercom number. This will turn on the MESSAGE light on the other phone, and the other person can tap that button to automatically call you back.

If you get a busy signal when you call an intercom number, you can signal the other person by dialing 1 (if that phone is programmed for System Call Waiting (above).

I was told by an AT&T rep that the auto attendant can forward calls to another 984 phone to leave messages for that person. Your original OGM (out going message) on the designated Auto Attendant phone should state greeting and the names and the extensions. The caller presses the buttons for the person they want to reach and their call is forwarded to that extension. That extension, if unattended, will have an OGM telling the calling who they have reached and to leave a message. This feature can only transfer calls to other 984 phones only.

I am not sure exactly how to do this on your system. My guess would be while talking to the person you press the voice mail button then either enter the extension number or if you have a direct button for that persons extension press that. Make a test call and try it out.
