The phone is not ringing when there is an incoming call. I can see the red LED is blinking but no sounds. Speaker phone same thing. Ring type --> play doesn't give any sound either.

Check make sure ringer is turned up,push speaker button then push volume button a volume thing should show up on the screen,keep pushing volume button and it will. Increase the volume.ty.

You will need to go into programming and set all the phones to ring.
Log in: Feature **266344, 266344
Scroll to Configuration > Line Access > Enter set number > Scroll to Ringing> Then go to each line and set it to ring.

Follow the below instructions and you can remove the vibrate state. I have included a link to download the phone's manual as a PDF file.

The two short rings is telling you that the call is either a transfered call (answered by someone else and transfered) or answered by an auto attendant and transfered. Watch the ringing phone when the call comes in and see if the intercom LED blinks.

Your phone is not programmed to ring. call local dealer for programming change.

if you having distorted sounds even if you change the ring style and deafault ring tones' the problem is the speaker buzzer of your phone....:D

This is a phone system phone and each station you want to ring when a certain phone line rings has to be programmed into the system. This is not something you can change at the phone itself. You will either need to pay a company to make programming changes or locate a programming and installation manual for your phone system (not the phone) and try to re-program it yourself. If you have not done this before it will not be easy but it may be worth the effort so you can continue to make your own changes instead of paying someone $200 per hour to do it for you.

 

There is also the remote possibility your phone's ringer is broken. You can try swapping your phone with another of the same type and model to see if it will ring.
