Need Motorola Timeport 280 Microphone

[Sunil]

I have Motorola Timeport 280 GSM Tri-band cell phone. The condenser
microphone seems to have become faulty as callers cannot hear me speak.
The phone works fine when I plug in an external headset+mic combo.

The microphone is the solderless type and has the numbers "64C07" on
its side. However, I cannot trace these to any equivalent or
manufacturer.

Any help shall be greatly appreciated.

Thanks.
