Well the first problem is that the method is actually get_NetworkAddresses.
The second problem is that the last parameter to the method is the address
of an actual VARIANT. My guess is that -- since the sizeof your array
exceeds the sizeeof a VARIANT, the information probably does get written to
it as a (VT_BSTR|VT_ARRAY). Presuming a success return code. The third
problem is that you never seem to check return codes at all. The fourth
problem is that IRTCSessionChangeEvent::get_State takes the address of an
RTC_SESSION_STATE.

its code is followed:

IRTCClient *m_Client ;
void CMyDlg::OnRTCSessionStatechangeEvent(IRTCSessionChangeEvent* pEvent)
{
BSTR bstrIP[20] ;
IRTCSession*pSession=NULL ;
RTC_SESSION_STATE enState ;

pEvent->get_State(enState) ;

switch(enState)
{
  case RTCSS_INCOMING:

m_Client->get_NetworkAddress(VARIANT_TRUE,VARIANT_TRUE,(VARIANT*)bstrIP) ;
    //
m_Client->get_NetworkAddress(VARIANT_TRUE,VARIANT_FALSE,(VARIANT*)bstrIP)
;
  //
m_Client->get_NetworkAddress(VARIANT_FALSE,VARIANT_TRUE,(VARIANT*)bstrIP)
;
   //
m_Client->get_NetworkAddress(VARIANT_FALSE,VARIANT_FALSE,(VARIANT*)bstrIP)
;

}
}

I saw the MSDN' comment and tried differant combination of first two
parameter .

but I can not get IP .Why?

hi:
I can not get address by calling get_networkadress of RTC Client

thanks in advance

So can you post your code and the HRESULTs you get along the way?
