Hi,
I am very much new to TAPI, currently i am working on TAPI. I have developed one client application which will talk to TSPSRV and will able to recieve call related events from the CTI manager.
But i am not able to recieve the ip addresses of the phones (lines) along with the events.
I have tried with the LineDevSpecific function, I am able to recieve LINE_DEVSPECIFIC event, but i am getting null value in the second parameter.
Here i am copying the code snippet what i am using in my application :-
I have used the below code snippet for setting the Linestatus messages for all the opened lines.
lReturn = lineSetStatusMessages(hLine, LINEDEVSTATE_DEVSPECIFIC,LINEADDRESSSTATE_DEVSPECIFIC);
if (lReturn != 0)
{
LogMessage(__FILE__,__LINE__,ERROR_LOG_LEVEL,"TAPI failed to Set Status Messages\n\rError Code for= %lu",dwDeviceID);
}
static CCiscoLineDevSpecificSetStatusMsgs CiscoSetStatusMsgs;
CiscoSetStatusMsgs.m_DevSpecificStatusMsgsFlag = DEVSPECIFIC_MEDIA_STREAM;
LONG dwRequestID = lineDevSpecific(hLine, dwDeviceID, NULL,CiscoSetStatusMsgs.lpParams(),CiscoSetStatusMsgs.dwSize());
I have used the below code snippet for decoding the parameters:
CiscoLineDevSpecificMsgType MsgType = (CiscoLineDevSpecificMsgType)(lpMessage->dwParam1 & 0xff);
if (MsgType == SLDSMT_RECORDING_STARTED)
{
ULONG ulIP = (ULONG)lpMessage->dwParam1;
CString str;
str.Format(_T("CISCO SLDSMT_RECORDING_STARTED: IP = %u.%u.%u.%u"),
LOBYTE(LOWORD(ulIP)), HIBYTE(LOWORD(ulIP)),
LOBYTE(HIWORD(ulIP)), HIBYTE(HIWORD(ulIP)));
}
But I am getting second and third parameter of lpmessage structure as 0.
Can one help me out this ASAP where i went wrong, because as it is very urgent requirement for me..
Thanks
Venkatesh.

For media streaming, you will be looking for the SLDSMT_START_TRANSMISION and SLDSMT_STOP_TRANSMISION events, not the Recording events.

Hi David,
Thanks for your immediate response on this..
Sorry, I am not recieving SLDSMT_START_TRANSMISION and SLDSMT_STOP_TRANSMISION events. Please look at the code given by me in the previous post and let me know where i did wrong..
Your help would be much appreciated....

Have you tried to use Cisco LineDevSpecific extension
SLDST_SET_STATUS_MESSAGES to enable CALL_DEVSPECIFIC_RTP_EVENTS bit so
your application can receive RTP event ?

What is the Difference if we do lineNegotiateExtVersion(hLineApp,dwDeviceID,dwApiVersion,0x00010004,0x00020001,&dwExtVersion)
lineNegotiateExtVersion(hLineApp,dwDeviceID,dwApiVersion,0x00010004,0x00040000,&dwExtVersion)
What will be the changes in receiving events for LINEDEVSPECIF or effect on any other events.
Is it correct that if we do first one: we receive SLDSMT_START_TRANSMISIONevents with line handle and
if we do second one : we receive SLDSMT_START_TRANSMISION with call handle.
or if the dwExtVersion returned by that lineNegotiateExtVersion matters in receving call handles and line handles for SLDSMT_START_TRANSMISION events.
please reply.
