Volume control I can't hear the person on the other end of the phone unless I have the phone on speaker. can only here person on other end of phone if i have it on speaker. I cant hear anything on my phone, when i try to make call, i cant hear anything whatsoever unless i put it on speaker phone. I dont know what to do!!!

Bad Speaker? That's what mine did when the speaker was bad. Try Speakerphone, seriously, then update me!

On the left hand side, there is a slider and two buttons below it, press the upper button to increase the volume. If that doesn't help take it to an authorised apple centre and let them help you.

maybe by mistake you reduce the volume on the iphone.

try the following during a call press on the right control up volume to see if that improve your sound.

if that doesn't work you should go to an apple store or your cell provider.

It is possible. I have ATT 945(?) 4 line phones that communicate via a DSL-like signal between units to do special things like intercom, etc.

What I have in my setup is that I have a seperate line from the point of entry of my phone line to my DSL modem.

I then have TWO stacked DSL filters PER LINE that feed the main phone line running to all the phones.

Be AWARE that when using the speaker phone there is a modulation of the gains both directions. When you talk OR have a noisy background noise, the gain of the speaker is cut down to prevent feedback. And when you go silent, the speaker gain is increased for you to hear the other side of the call. Essentially it takes as much discipline as the old two-way radios... one talker at a time with these speaker phones AND very little background noise.

In this case check the volume of you're Handheld, If it is low, Increase the volume and check still if it is not working you need to walk into the service center to check the speaker of you're Handheld.

The problem could be due to some contact error in the headphone jack of ur phone. Please re insert the headphone and remove it. Now try making a call with the speaker volume put to maximum. Dont forget to rate the solution. Thank You..

Your speaker could be going out.  When making a call press the $ button to activate the speaker.  See if that function works.
Adjust the volume with the volume control on the right  side of the as needed.

There may be some problem with your speaker.It may be dusty therefore it's not working properly or sometimes it also happens due to network problem.

You can turn the earpiece sound up, but I think you have to do it when you receive a call. The < and > keys on the side of the phone turns it up or down, you will see some circles to indicate how high or low it is set at.

The earpiece speaker has gone bad. Unless you have access to a replacement speaker and can solder you will have to take the phone to you nearest Motorola service center.
