    I had the same problem. All of a sudden, I couldn't hear anything when calling but the people on the other end of the call could hear me. AT&T wouldn't do anything. I figured out myself to get a headset and use the bluetooth capabilities the phone offers, or use speakerphone which can get annoying.

    I have the same problem. When I dial a number, I can't hear the phone ringing. If someone calls me, I can't hear them. All this started when I was checking out the blue tooth settings in hopes that I could get my blue tooth to work.

I had the same problems that hottytoddy TWICE with 2 different phone sets. The original one came as a bundle with a 2-yr contract with AT&T. They exchange the 1st one which lasted 9 months with a refurbished one which lasted 93 days. After that they agreed to replace it with a Nokia 2610 for free, as they consented hottytoddy issues are known and not fixable. Sorry.

I canot hear it ringing when anyone calls. there is a dial tone,and i hear it ringing when called from another line but no ringing on my end

Because you said you have a dial tone I'm guessing that this is a land line (home) telephone. Make sure that the ringer volume is turned up. You may have to search for it but it is located somewhere on the phone. Plug another phone into the same jack and if this unit work replace your phone(very cheap). Still not working then you may have a defective phone cable which must be replaced.

Hope this help with your problem.

No sound when dialling out

for those of you having this problem, what you need to do (as i so annoyingly discovered) is to 'delete all' in your previously called numbers, then it dials out just fine. lame, but it works. :D

My phone has no sound

when you say no sound, that is very vague.. No sound when it rings, no dial tone, what do you mean when you say no sound.
Sorry , but that is too little information to help you.

I Think There maybe a problem with the internal speakers.does anyother sound work or is it just the dialing tone and voices?
if its just dialing & voices check in the call menu that sound IS NOT muted.This may solve the problem.

if no sound works at all,maybe its is damaged but you havent noticed? Take it back to the shop you bought it from and tell them about the problem,afterall a phone that you cant ring people on is usless! Or ring your network provider to see if it may be repairable under warrenty.

Hope That Helps.
Good Luck
