Re: Panasonic 816 phone system

What you need to do is set the number of rings before answer on the phone to a number greater than the number of rings it takes before AT&T answers (for example, set AT&T to answer after 4 rings and the phone to answer after 5). Some phones have switches on them that allow you set the number of rings. Some make you set the number through their software. Look on the body of the phone, particularly the sides, for that switch and set it to the biggest number it offers.

I have a Samsung prostar 816 phone system and when someone calls in I see a flashing light but no ring in my zone. Tried to reprogram using the guide I saw on the fixya answers but still does not rin

I found a manual for your phone here;
and it would appear (page 2) that your phone / zone is operating in "Night Service Operation" which presumably mutes the ringing tone.
You can download this file (pdf format) to your computer for future reference.
Hope this is helpful, if so would you please register that with Fixya

The coord connecting to the phone jack will not turn on the phone, is there an actual ac plug for this phone?

Since a 7456 is a phone for the Panasonic KXTD digital phone system, what are you plugging it into? It requires at the least, a TD-308/816/1232 KSU in front of it.

I currently use a Panasonic KX-T7431 at work and I wnat to either know does it have an answer machine function within the phone or can I buy one to add to it , we cusstenly do not have any faciity for...

Generally, a 7431 phone plugs into a Panasonic KX-TD phone system cabinet. The 1232 starts as an 8 line 16 phone cabinet, the 816 a 4x8, and the 308 a 3x8. To those systems, you can add a TVx Panasonic brand voice mail system, or even a plain old ansering machine. Both would need to be probrammed by someone familiar with ringing and intercept groups in system programming.

A quick call to your Panasonic installer or dealer would be the best, as it's beyond the scope of this forum to provide instructions.

Message Waiting Indicator (MWI) light stays on since VoIP

There maybe different MWI options available in the phone's set up menu on the base unit. If so, see if the different options perform differently. Your phones are probably set to "FSK" (frequency shift keying) for MWI but IIRC, U-Verse uses the "Stutter" option. Also, in addition to talking to the installer, call ATT tech support. If the problem is in the signalling they may now have programming options on their end to resolve it.

If you're in the U.S. try and search for a Panasonic TD dealer.

If you really need help, get the model number from the cabinet and comment back here. You could start by making sure that the plug is directly connected to an AC outlet and disconnect all the cables from the 816 has modular, the 1232 has Amphenol cables.

The red power light will blink before it goes solid on a properly initialized system.

Panasonic 816 reduce from 4 to 1 ring before auto attendant ans.

You can voice mail to answer after one ring.
You will need a programmer to program ringing.

Voice mesage

What manual did you download, where is the message located, and what is it recorded on?

A 7433 phone is just a phone, it has no messages. It is connected to a TD-816/1232 Key Service Unit and a TVS/TVM/TVA voice mail system if it's Panasonic branded.

When you call in to the TD system, the voice mail answers the call and plays the Auto Attendant greeting. Is this the one you want to change? Or do you want to change the greeting that you get after the AA answers any they dial your extension?

Each of those messages can be changed from the Message manager's box or from your own mailbox, using the codes and passwords supplied at installation.

Samsung Prostar 816

The battery is dead and will not maintain system programing after a power outage. If the battery is not replaced this problem will occur everytime the power goes out.
