Q: iPhone 4S - Outgoing call no audio

Well the AT&T help line was USELESS.  The guy could not even get straight what i was telling him was the problem.  He also said the problem has not been reported by any other users and told me to remove the battery to reset the phone!  I sarastically asked, "how?" and he put  me on hold to find out.  Yet here is 113 pages worth of complaints about it.  ANd these are just the people who chose to post!  I ended up hanging up on him and plan to go to the store tomorrow.  Do you suggest I go to the AT&T store or the Apple store?  I suppose only the place i bought it from would replace it.

THe problem has been getting worse since I got the phone.  It used to be intermittent.  Now it seems permanent.  It automatically switches itself to speaker phone and no one can hear me.  If i try to take it off speaker phone, either it refuses or all sound disappears (i can't hear the other side either).  HOWEVER, i found my own work around.  If I use the phone's browser, and make calls with my google voice number, all audio works properly.  Has anyone else experienced this?  That should mean it has nothing to do with the audio and something to do with the calling features. 

Also, the phone does re-recognize bluetooth accessories.  Even when it has connected before, i have to go in to settings, make it forget the device and re-search for it. 

mine is C39 as well having the same problems as you 

I have the same problem with my iphone 4s on 100% of outgoing calls. Serial number C38, purchased Dec. 21st.  The phone says it is connected, but I can't hear the other person.  I do hear an echo of myself occasionally.  I can get the phone to work by turning on the speaker.  I have never used bluetooth, and the problem started before I turned on Siri.  I bought the phone with best buy without their warranty assuming that apple would stand behind thier products.  Huge Mistake. 

I am incredibly frustrated that this issue has not been publically addressed.  The apple store in Toronto was also completely unhelpful, and wouldn't even admit this was a common problem.

apple need to check their forum regularly a topic over 150k views with more than 1600 replies complaining & this isn't a problem ? if i knew about this i would've have kept my s2 but i never imagined such a basic feature as calling to be a problem

Have the same problemen with my iPhone 4 on iOS 4.3.3 :s

Hardware: iPhone 4 16gb black december 2011

iOS: 4.3.3

Now I've upgrade my phone to iOS 5.0.1, at the moment I haven't got the audio problem again when calling.

Let us hope it will stay away...

This must be an iOS5 problem. I have an iPhone 4, bought in June 2011. No problems with it at all until now. I upgraded to iOS5 in October when it was released, but it was only two days ago in January that my phone started having this problem. It began in the middle of a call - I was 5 minutes into a call and then I just couldn't hear a thing, but the person I was talking to could hear me. Turning on speaker or headphones work, but it's just too annoying.

Will try full restore tonight or tomorrow and see if it works as some people on iPhone 4 have said it worked, but Apple really need to solve this problem soon...

My wife got an iPhone 4S yesterday and it had this problem straight out of the box. The problem is alllll the time on hers, and it doesn't matter if it's incoming or outgoing.

That's why my next phone is an Android.

My wife has had an iPhone 4S on the UK network t-mobile for just over a month. This call audio issue happens around 50% of the time. Reports seem to be that iOS5.1 won't fix this issue which is just unacceptable. An iPhone is an expensive item and doesn't work as a phone!!

Tapping the speaker phone button is a workaround but why oh why hasn't Apple respond to this clearly massive flaw? The issue is clearly to do with the various types of audio out getting confussed - headphones, speakerphones and regular phone ear hole.

When will this problem be fixed??

Well there's nothing left for me to dow now. I hard resetted, resetted the complete setting, restored the IOS to factory default, tapped over the speaker and mic, disabled the Siri including raise to speak, charged and discharged battery, hooked and unhooked the ear phones, tried most of the settings combinations... whatelse left now?

Do I now need to drive over it?

Iphone 4S with IOS 5.01 with audioproblems.

I think i've got rid of the problem.

Yesteday I've installed the IOS 5.1 Beta2 version, and so far i get no problems.

But i need to try it in the car with bluetooth so i get back.

I'm having the same problem with 4S in Brazil. At least three calls by day with no outbound audio.

I'm having the same problem with 4S in Russia. Serial number  C39

My wife's phone 4S - 16 GB white (Serial starts with C39) has the same problem. The phone was bought from US and we are living in Turkiye. We need to find a way to send US for the replacement. APPLE wake up and explain something. At least clarify if it is software or hardware related. I ordered one more 4S 64 and cancelled it because of that issue. You are losing your fan customers!!!

Replying to the first post in order to keep the original alive and the counters ticking!! 32 Days - bang goes the replacement.

iPhone - but without the phone it seems.  Exactly the same problems as most posts, no audio when making calls albeit the phone is now dropping the network provider as well meaning can't make calls at all. 

When making calls to the 4s it rings from the caller but not on the 4s and no sign of an incoming call.

I notice a comment by 'richcortes' on November 6 2011 he mentions loading from a 3g - could this be a connection? We have done the same with ours? Anyone else?

Stick with the iPhone 4......

Come on Apple!!

Resetting the network settings on the phone works for me for a few days. Maybe because I don't make a lot of calls, I get more time out of the reset before the problem kicks back in.  I get the problem intermittently.

my serial number starts with C39

this  is my second 4S.  The first one didn't have this problem. I returned it because the speaker was bad. Problem started immediately on the "new" phone.
