you can try restoring the phone from backup
you can try restoring the phone as new
other then that you will need to take a trip to your local apple store and get a replacementmacbook pro 17 inch - iPhone 4, Mac OS X (10.6.4)
Currently Being ModeratedDec 27, 2010 11:25 AM (in response to sn4p2k)I started having this issue just yesterday. I don't have any water damage and haven't dropped my phone. I'm not sure whats going on. It was working fine and then, my friend called and I could hear him perfectly and they could not hear me at all. I'm in the process of syncing and backing up my phone and then going to restore. hopefully that clears it up. We just had a HUGE SNOW STORM in New Jersey/New York and my cars are snowed in and I can't get to an apple store. So I have to wait to get my phone fixed/replaced. I'll post back once I finish restoring, to let you guys know if that worked or not.Aluminum Macbook, Mac OS X (10.6.5), My first Mac and I love it!
Currently Being ModeratedJan 22, 2011 10:18 PM (in response to idelgado782)I bet your phone was updated to run 4.2.1.
I have the same problem. I haven't been able to fix my replacement phone with any sort of reboot, restore etc since it upgraded to 4.2.1. Awaiting 4.3!iPhone 4 with iOS 4.2.1, iOS 4
Currently Being ModeratedMar 4, 2011 1:11 PM (in response to figgs)ALL THE FOLLOWING IS MY SUPPOSITION ONLY - MOVING AND INSERTING REPEATEDLY THE MIC JACK WORKS FOR BRIEF MOMENTS
Ok, I have the same issue but I fortunately discovered WHY.
In MY case [could be yours but also could not] the problem started with some malfunctioning of the vibration. Once in a while the vibrate thing stopped vibrating. This means in the part of the phone where the mic/phones jack goes there's a vibration module that isn't working properly. This causes the vibration module to jog and move excessively when it works, and I left my phone vibrating due to many and many calls on my bed cos I was doing something else.
All the vibrations probably caused the very close microphone/phones jack hole to have the final part to be faulty, so that if you plug in the mic/phns with strength and move the jack when it is inside you start hearing something. If you press it a lot, you'll see something changes, and if you try to make the final contact of the mic/phns hole come UP towards the top of the phones -just to to be clear: to go OUT of the hole, to be pulled instead of pressed in- you hear other changing. PROBABLY that final metal part has been made loose and so the communication works only when it returns into the first, factory brand-new position. With the sound recorder you can record and HEAR easily; skype does work but the phone has some more direct connection with the jack/hole and that's why it does not work. It seems like it switches extremely fast between phones and normal phone speaker. An headphones trigger or exclusion command in the settings probably could fix it. So it's a mix between a software and an hardware problem.
Try moving and inserting repeatedly the mic jack.MacBook - MacBookPro, Mac OS X (10.5.5), Glassbook

Hi, i have 2 iphones 4 and all of them have this microfone problem during normal calls. They are runing with the iOS 4.3.3 and the problem still there. What can we do? Any Apple position?

Me as well! This seemed to happened after last firmware update 4.3.3 and as you write, the microphone and or headset works for all othe apps including Skype. I've also posted on this subject but our posts haven't been connected! What's Apple doing about this? I have a £600 telephone which is useless as a telephone...

Moving the mic jack etc didn't work, but yesterday I received a call, answered it, and they could hear me!! I haven't done anything specific with the phone except, charging, listen to music w and wo headphones and installing app. No OS update and certainly no dropping the phone on the floor. So, now I'm in 'heaven', but for how long?

I too am having the exact same problem.
On May 30, I had this problem for the first time. I was on a phone call, when all of a sudden in the middle of the conversation, the other party couldn't hear me. After a few re-attempts to make the call 'work', we were able to complete the conversation over FaceTime without any issues.
For the next 2 days, my phone was a useless brick in my pocket. Skype/Evernote/Voice Recorder all work great, and I could hear the other end just fine. I rebooted, I restored from backup, my next step was going to be to take it to the Verizon store and leave AT&T..
The morning I was planning to visit the Verizon store to change networks and get a new phone, I received a phone call and the phone was working perfectly fine again. Baffled, I assumed the problem was solved.
Fast fwd to today (June 12) I was on a call this morning with my bank, and all of a sudden the other end couldn't hear me. I had the entire call on speakerphone, so I wasn't touching the device. I ended up having to end the call as the other party simply couldn't hear me at all. Every call I've tried to make for the last 5 hours, has resulted in the same problem: they can't hear me. I've been in different parts of LA all day, so I've been on different cell towers, so I don't think it's the network. Again, Skype/FaceTime/VoiceRecorder all work fine. There is clearly a defect with the phone app (or something running in the background that is causing a conflict of sorts) that is causing it to mute out our voices.

*** is up that that? I have the same issue on my wife's phone. Only started last night. Stopped working in a call between us. I just stopped hearing her. Or more correctly her voice wasn't going out.
Tried other apps and they all work fine; talking Carl, voice recorder, I don't use skype but my voice app works, as does shazzam!!! But not the phone.
We've looked at it again today and still no go. But talking Carl and shazam fine.
I just tried the above "tip" about squeezing the top of the phone during the phone call. Sure enough call didn't work, touch the top and whammo! But a second later it was dead again. Make you feel it's a wiring issue. But everything else works fine.
What's the go with that?

I started having this problem after upgrading to IOS 5. It sounds like very loud static or crosstalk at the other end. It happens after I use Skype and I have been able to fix it by doing a reset. I need a better solution as this seems to be a problem between Skype and the phone app.

Hi. I have the same issue. About 5% of the time it will work for the start of a telephone conversation, but 95% I get nothing. All other apps that use the microphone work perfectly, no noise, no crackling or anything. And also I still can't be heard when using the Apple earphones/mic.
So clearly not hardware, methinks.
Stupidly I waited for the ios5 update, which didn't fix it but now my phone is out of warranty, and if any of you have tried to get an iphone fixed under insurance knows it is a long-queue'd nightmare. I refuse to pay to fix a fault that is clearly not my own.
Anyway, I really hope that Apple will fix this issue soon.
A few notes about the posts above - if you're getting crackling or low volume or any apps besides phone don't work - you've probably got a slightly different issue. Also, I tried that trick of putting in/pulling out the mic jack and it did work - although it could be just a coincidence.
If anybody finds a software patch or fix for this issue please reply to this comment with it!
