Parties cannot hear each other
One of the following issues sometimes or always occurs when you conduct calls. It either occurs right at the beginning of the conversation or sometime during the conversation, for example after five minutes:
- You do not hear the other party.
- The other party does not hear you.
- The parties cannot hear each other.
This may give the impression that the telephone connection has been terminated. However, the connection is still active. You can see that it is because the telephony LED on the FRITZ!Box remains lit. The LED does not turn off until you end the call by hanging up.
Simply proceed as described below. After each measure, check whether the problem persists.
