6210 intermitent microphone problem


Hi,

Sometimes my microphone doesn't work. I'm in a call, a talk for 30sec-1minute and the other person can't hear me anymore.
Most of the time the phone works ok, but from time to time i have this problem with the mic.

Any ideas?

80% no need 2 change > Resold COBBA, if the Audio A/D-D/A convert system fails sometimes.
