The phone's darling Apple has added a new bug that has touched the problem of battery life and expectations known.

Many users complained on Apple's support forum that they can not hear the other person's voice when making outgoing calls.
There has not in any way to completely fix this bug. Temporary solution is that users can turn on the computer speakers, then back off to be able to use the headset.
According to Gizmodo, the phenomenon is caused by driver error between 5 and hardware iOS iPhone 4S. IOS version 5.0.1 has been sent to the developer. Hopefully these errors will be treated in the next few weeks.
