Anyone can help to increase the speaker phone Volume

[7up]

The speaker phone volume is so low that I cannot hear people's speaking in open area. Does anyone know how to tweak it to make the speaker phone volume acceptable? Strange, for music and ringtone, the speaker volume is OK, For phone call with speaker enable, the sound is totally unacceptable.

However, the problem is different, the phone vol is sound good, but once I switch to speaker phone or using Video Call, the speaker phone volume is totally unacceptable. Does someone know the registry to make the speaker phone volume better.
