Hi anyone:
Follow is the example included in Cisco provided at
http://www.cisco.com/univercd/cc/td/doc/product/voice/vpdd/cdd/3_1/tapi/tap_exmp.htm
DWORD retExtVersion;
if (bTermMedia) {
TRESULT tr3;
tracer->tracef(SDI_LEVEL_DETAILED,
"TAC: lineNegotiateExtVersion - appHandle = %d, deviceID = %d, API ver = %d,
HiVer = %d, LoVer = %d\n", CtLine::GetAppHandle(), lineID,
CtLine::GetApiVersion(lineID),
0x80000000 | 0x00010000L,
0x80000000 | 0x00020000L );
tr3=::lineNegotiateExtVersion(CtLine::GetAppHandle(),
lineID, CtLine::GetApiVersion(lineID),
0x80000000 | 0x00010000L, // TAPI v1.3,
0x80000000 | 0x00020000L,
&retExtVersion);
but app run here, I found retExtVersion is 0x00000000, I realy don't beleave it,
when I view the debug info at c:\temp(I use Cisco TSP3.1),YES,info is:
12/26/2001 15:04:24.816 CiscoTSP001.tsp| TSPI_lineNegotiateExtVersion() TSPI_lineNegotiateExtVersion returns = 0x00000000
How can I do?
Can anyone tell me how to resolve it?
Thanks
