The PHONE_LINE_VU_METER_CALLBACK_PROC data type is used by the telephony API to define a callback procedure that is registered with the telephony engine. This callback procedure is specified when application software calls the SetPhoneLineVuMeterCallback(VoipMediaEngine, Int32, VoipMediaEngine..::.PHONE_LINE_VU_METER_CALLBACK_PROC, Object) API procedure.

This callback procedure allows applications to receive real time full duplex digitally mixed phone call VU meter sample block data on a per phone line basis.
