iPhone 4S - Outgoing call no audio

Picked up a Verizon iPhone 4S - 32GB and on about 1 in 10 calls I get no outbound audio when dialing. Call shows the timer counting as if the call is progressing but absolutely no ring back and cannot hear the party on the other end when they answer.


Anyone else having this issue? I've found a few forums online stating people have had luck hitting the speaker button on and off to get it working again but it hasn't failed in the past 20 minutes for me to test that theory..


Thanks...

Same issue -- on my second 16gb white iPhone 4s (AT&T). Was given a new one at the Apple Store a couple days ago and this one does the same thing. Called today and they had me do a hard reset. I have restored, reset network, etc. and still does it. Can't seem to get an answer from Apple as to if it's a known issue or not. They did try to upsell me though and get me to purchase AppleCare.


Starting to regret pre-ordering and getting a launch day phone. Prefer to wait until the kinks have been worked out but my 3Gs was dying.

1990reds, do you use a BT headset also? I believe TheAmdMan is correct, it revolves around the bluetooth headset. Mine was working fine this morning, until I walked out of range of the headset (and hence it disconnected). Once I did that, the issues started.


Will keep trying to get a reproducible case, but was curious if you're using a BT headset...

I do not use a BT headset and have never even toggled the BT on in the menu. As long as I hit the speaker button and then switch back, it works fine.


I had no luck resolving the issue with Apple today, then got disconnected the second time I was on hold with them. AT&T was apologetic, but couldn't fix the issue for me and they don't have any stock right now to give me another 4s.


Really irritating, but at least it works if I use the speaker button for now. Everything else about the device has worked fine.

I am having the same issue on a 4S 16GB on a Vodafone UK netwrok. I get the call screen and can see the timer but no sound. Next time I tried the speaker Icon was highlighted and I was not able to switch to handset. It seems to be very strange behaviour.


I did have it connected to a BT headset but when I tried to call the headset was sitched off. It seems the phone still thinks it is connected to BT headset!!


Anyone found a solution?

Yes, this is the same behavior I am seeing. I believe Siri is also involved somehow. Like, if you talk to Siri, then disconnect the BT headset, the "audio out" gets lost.


The last time I was stuck in this mode, I talked to Siri again, and the audio fixed itself.



Still hunting for a reproducible case, then should be able to find a solution. But definitely seems like a software (not hardware) issue.

I have had my phone since Friday Oct 14th and today I experenced this issue a couple times today. Same thing as you guys are experence. No audio on the handset ear peice but the other party can hear me fine. I can switch over to speaker which works, Sometimes going back to the ear peice it will correct itself. I did a hard reset and have not had the issue since but have only made a couple calls.


I called apple about something else today and mentioned this, they didnt have much info. Im thinking it might be a simple software glitch and it will be resolved in a update to iOS
