Issue with SIPX_LINESTATE_INFO

[Bhaskar Raghavendran]

Hi,

I am initializing the event listener using the 

sipxEventListenerAdd(sipXinstance, SipCallbackProc, NULL);

In my call back function, I am trying to filter the Line State Events:

bool SipXConnector::SipCallbackProc(SIPX_EVENT_CATEGORY eventCategory, void* pInfo, void* pUserData)

{

switch (eventCategory)

{

case EVENT_CATEGORY_LINESTATE:

return SipXConnector::getInstance()->HandleLineStateEvent((SIPX_LINESTATE_INFO*)pInfo);

default: 

return false;

}

return true;

}

bool SipXConnector::HandleLineStateEvent(const SIPX_LINESTATE_INFO* pLineInfo)

{

switch(pLineInfo->event)

{

case LINESTATE_PROVISIONED:

break;

case LINESTATE_PROVISIONED_NORMAL:

break;

case LINESTATE_REGISTERED:

break;

case LINESTATE_REGISTERED_NORMAL:

break;

case LINESTATE_UNREGISTERED:

case LINESTATE_UNREGISTER_FAILED:

UnRegister();

break;

}

return true;

}

The problem I am facing is in the HandleLineStateEvent method above.

The pLineInfo object does not show the event and the cause (the breakpoints on the case statements do not hit due to this), but shows the rest of the data, although the SIP extension gets registered successfully on the server. 

I am not sure what I am missing here. Please enlighten!

Thanks!

Hi Bhaskar: Your event handler looks fine to me. I am not sure what your UnRegister method does, but just to be clear the LINESTATE_UNREGISTER* events are not going to occur until after sipxLineRegister(lineHandle, false) is called. Are you getting the LINESTATE_REGISTERED state? Did you invoke sipxEventListenerAdd before the line was registered or at least before the line was unregistered? Also just to be sure we are talking about the same code base, what svn repository are you workinng off of? You may also find sipxEventToString to be useful in debugging your event handler.

Hi Daniel,

The Unregister method basically calls the sipxLineRemove and sipxUninitialize. The reason why it is called in the switch case is because, I am calling sipxLineRegister(sipxLine, false) and I am expecting the LINESTATE_UNREGISTERED / LINESTATE_UNREGISTER_FAILED to occur after which I call Unregister(). This is just a test app though.

I am working off of the code base from the google:  code.google.com/p/sipxtapi/ 

The SipXEventListenerAdd() is invoked just after the sipxInitialize() method and before the sipxLineAdd() and sipxLineRegister().

The main issue I am facing is that in the HandleLineStateEvent, the SIPX_LINESTATE_INFO object (pLineInfo) displays all the other data, but not the event and the cause, which is why the switch-case statement doesn't enter in that method.

The SipXezPhone is the same code base when executes seems to be working just allright. I am just not sure what I am missing.

The libraries that I have included are the sipXtackLibD.lib sipXtapid.lib sipXportLibD.lib.

The headers I have included in my code are: tapi/sipXtapi.h and tapi/sipXtapiEvents.h

I am sure I must be overlooking something, but have no idea what it is.
