The PHONE_LINE_RECORD_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 StartPhoneLineRecording(VoipMediaEngine, Int32, Boolean, Boolean, Boolean, Boolean, Int32, String, VoipMediaEngine..::.PHONE_LINE_RECORD_CALLBACK_PROC, Object) API procedure. This callback procedure allows application software to gain access to full duplex digitally mixed sample block data (phone call audio) on a per phone line basis.

This callback procedure allows applications to receive real time phone call recorded data.
