Q: iPhone 4S - Outgoing call no audio

I had AT&T iPhone 4S 64G with same issue.  After reading several forum discussions yesterday, I tried switching the speaker on then off as suggested.  This work-around worked but was still unacceptable to me.  I made an appointment at the nearest Apple Store Genius Bar.  They did some diagnostics and told me that the phone checked out fine.  However, they gave me a replacement phone with no further questions asked.  I figure they must be getting quite a few returns judging from how quickly they agreed to replace.  I have not had any problems with the new phone.

I have this problem intermittently. I go days without it happening, then it happens again. It just now happened again and I decided to search for the issue...lo and behold, I find this thread. I know I have tried toggling the speaker on and off during one of these "no audio outgoing calls" and that hasn't seemed to work for me...I'll try it a few more times, since it seems to work for most people. I have a black iPhone 4s 32GB.

I'm going to add my post to this thread so we have at least one large thread with a list of the problems (there are MANY other posts on the board, but this one appears to be the largest one I've come across.) I have an AT&T, 64GB, White iPhone 4s. Intermittant audio on outgoing calls is the issue. I have been through all of the listed fixes -- reset network settings, total reset, restore, DFU restore. All to no avail.

I'm in between on going through the trouble of going to my "local" Apple store (2 hours away) to roll the dice on getting a new device (although the last tech I spoke to said they would note it in my case.) It also appears to me that replacing the phone only fixes the issue in 50% of the cases. Hopefully, if we continue to pile up complaints it will be addressed, HOPEFULLY by a software fix (which is likely.) We will see.

Are you sure about this? Myself and others in this thread who have gotten a replacement seem to be overwhelmingly reporting that the issue has completely disappeared.

I just tried to solve my audio problem with a DFU restore to "a new iPhone". But it did NOT fix the problem at all.

Didn't fix mine either.

I've replaced mine twice already, the problem persists.

BGR is reporting the issue today.

Hey Apple! When are you going to say something about this? It's the loudest topic on the iPhone 4S Support forum, people bought a phone with a major flaw, yet there is no acknowledgement that someone is working on a solution and what you think the problem is, it's been more than 2 weeks since launch and this issue started on day one. I would never again buy an iPhone at launch and before checking the support forum to see that all problems are resolved, maybe I'll start sticking with my old iPhone for 2-3 years instead of upgrading every year, maybe I'll look into android. Start taking responsibility or you'll start loosing my business.

I had an iphone 4s that worked fine then got another and when I call out it shows it is ringing but I cannot hear anything.  The person that I call says it is ringing on their end for a couple of rings then stops.  I talked to Apple support yesterday and they had no solution

Hello everyone!

Like everyone else here, I had this irritating problem on my iPhone 4S 32Gb White, which was purchased in France. Tried a restore about 4 times, no fix.

But I think I've managed to find a solution.

Go to Location Services -> System Services and turn OFF "Cell Network Search". Actually, I disabled everything exept "Compass Calibration".

After that, the problem seem to disappear. I made about 10 calls and the speaker worked properly.

Please write here if this solution help you, my iPhone seems to work fine.

PS: Sorry for possible mistakes, I'm from Russia.

I tried the Cell Network Search off and it didnt work for me.  I'm gonna go to the apple store soon and hope they got properly working replacement 4Ses.

Here is an update on my iPhone 4S 64GB.

Took it into an Apple Store over the weekend and described the problem with one way audio and explained what I had done to try to fix it. The genius replaced it without any further questions.

Have made a lot of calls over the last few days on the new iPhone, using built-in mic, bluetooth and plugged in headset - no problems whatsoever. Apart from this one fault, the old iPhone and new one performed exactly the same.

Just want to add that I frequently have this problem too.  Very frustrating when I have to text someone that I will call them when I can find a land line after I have tried to call them 10 times with no outgoing audio...

Hello there Apple! Say something! We all paid a lot of coin for this phone and we want answers!
