Where is V3M Microphone?

I have a V3M mainboard on which the Internal Microphone is very weak. While I have the block diagrams and layout of the Mainboard, I cant figure out where the Microphone is. I thought maybe it was part of the ringer/speaker but I have replaced that part and it does no good.
Is it practical to replace it?

To answer my own question (since nobody else did), the microphone on the V3M is mounted on the bottom of the PCB - Follow the air hole just below the # key.
A good solderer could replace it, but I fixed the problem by blowing compressed air into and around the mic inlet.
