futureoftapi,
what is the exact error code from lineOpen() ?
Where does the variable line come from?
Please provide a code snippet showing this.

Btw. you may want to use LINECALLPRIVILEGE_OWNER | LINECALLPRIVILEGE_MONITOR.

Please note that wave devices of voice modems driven by UniModem.TSP can only
work half-duplex, i.e. you can _not_ play and record at the _same_ time.

Can you reproduce the issue with TAPI Browser TB20 ?
Please post a TB20.log and enable Options/LogParameters and /ShowTimeStamps in
TB20.
