lineGetID Fails For Wave Device

[b***@gmail.com]

I have a TAPI application that talks to the Cisco CUCM TSP. The application places a call from a CTI port and when the call is answered it plays a recording. My problem is the call to lineGetDevice ID for the wave driver fails with error LINEERR_OPERATIONFAILED. My code looks like this:

BYTE by[TAPI_MAX_DATA];
VARSTRING* pVS = (VARSTRING*)by;
pVS->dwTotalSize = sizeof(by);

// Get channel information
LONG rc = lineGetID(lineHandle, 0, callHandle, LINECALLSELECT_LINE, pVS, "wave/out");

I also get the same error if I do the same thing using Microsoft's TAPI Browser.

Thanks in advance for your help.

Ben,
if you can repro the issue with MS TB20 then it is a likely a TSP issue that you may want to report to the TSP manufacturer.

If the DeviceClass simply isn't available then a LINEERR_NOVICE would be expected, but not a LINEERR_OPERATIONFAILED. This indicates actually an issue.
