I'm using code similar to this:
byte[] arrData = ... // get the wave data
IntPtr intPtrData = Marshal.AllocHGlobal( arrData.Length );
Marshal.Copy( arrData, 0, intPtrData, arrData.Length );
sipxCallStartPlayBuffer( callHandle, intPtrData, arrData.Length, false, true,
true );
Marshal.FreeHGlobal( intPtrData );
and this works, at least for short recordings.
