Cannot get my phone back on to ringing - Cell Phones

try to check ur call settings. look for hold durations

Did you try unplugging power cord for five minutes? often this fix the problem.

remove the power cable and put it back

Usually on the wireless phone their is a button to adjust the volume. It may say loud ring or soft ring. Or ring on or off.

quick solution, unplug the phone from the wall leave a minute, then plug back in. if an Alarm has been set this would in MMC 114, I have sent you a video explaining Alarm mode on the Prostar 816. or go to http://www.abbeytelecom.com for written copy.

Similar to someone else. There is a hardware issue. When I press on the camera lens area on the back of the phone, the sound comes back or gets louder.

take battery and the sim card out for at least 20 min. should help

Cycle through the menu until you see ringer settings, then follow the prompts.

To change the ringing on a prostar 816 you first need to be at a display set (doesn't matter what the extension number is).
with the handset down enter #20 the screen should say MMC DISABLED
1) enter in 1 2 3 4 1 # (that enables programming)
2) enter in #62 the screen should say day ring assn
3) press the line you wish to program
4) press the buttons for the extensions that you wish to ring (the ones in the right next to the handset)
5) press # when finished with the line
6) repeat steps 2 through 5 for the remainder of the lines you wish to change
The code for hold recall is #52
enter in your hold recall time in sec. and in a 3 digit format. i.e. 30 seconds = 030 a minute and a half is 090 and so on.
press # when finished

it sounds like the memory battery on the main board is no longer working which means that it'll happen again.

"Ringback" generally refers to the music people hear when they call your phone. You have to set that up thru Verizon (or other carrier).

If you're talking about ring tones (what YOU hear when the phone rings) that's easy. Look for a folder called "Rings" inside the Windows folder on your phone. If you put an audio file (wav, mp3, etc) in that folder, it will become available as a ring tone.
