Important: You must be talking on the phone Link.
Select: Control button Options > Mike off.
Switching microphone on/off
Your caller cannot hear your private conversations when the microphone is off. You can still hear the caller. Mike off appears in the MMI display.
Replacing a call
If you are already talking on the phone when someone else calls, the options Replace and Ignore will appear on the MMI display.
If you select Replace, the active call will be replaced by the incoming call. If you select Ignore, the incoming call will be declined.
The display in the MMI may remain for several seconds afterwards (depends on your type of phone). Should you use the function Replace or Ignore in the MMI system during this time, it is possible that the current call will be ended.
Note
The option Call waiting must be activated on your mobile phone for you to be made aware of incoming calls during a conversation. The call options depend on your mobile network service provider.
