Making a Circuit-Switched Telephone Call

XQTelephony* telephony = new XQTelephony(this); telephony->call("+9190000000000");

Get Notification of the call status change

   XQTelephony* telephony = new XQTelephony(this);
   
   // Connect lineStatusChanged() Signal to handleStatusChange() Slot
   connect(telephony, SIGNAL(lineStatusChanged(XQTelephony::LineStatus, QString)),this, SLOT(handleStatusChange(XQTelephony::LineStatus, QString)));
   
   // Our slot for handling telephone line status changes
   void MyTelephoneLineListener::handleLineStatusChange(XQTelephony::LineStatus status, QString number)
   {
       switch(status)
       {
       
           case XQTelephony::StatusRinging:
           {
          
           }
           case XQTelephony::StatusIdle:
           {
           
           }
           case XQTelephony::StatusDialling:
           {
           
           }
           case XQTelephony::StatusConnecting:
           {
           
           }
           case XQTelephony::StatusConnected:
           {
           
           }
           case XQTelephony::StatusDisconnecting:
           {
           
           }
           case XQTelephony::StatusHold:
           {
           
           }
           case XQTelephony::StatusTransferring:
           {
           
           }	
       }
       
   }

Get Notification for the Incoming call

To get notification for incoming call, the LineStatus of the call is StatusRinging

XQTelephony* telephony = new XQTelephony(this);

// Connect lineStatusChanged() Signal to handleStatusChange() Slot connect(telephony, SIGNAL(lineStatusChanged(XQTelephony::LineStatus, QString)),this, SLOT(handleStatusChange(XQTelephony::LineStatus, QString)));

// Our slot for handling telephone line status changes void MyTelephoneLineListener::handleLineStatusChange(XQTelephony::LineStatus status, QString number) {

         switch(status)
         {

// get notification for incoming call

                         case XQTelephony::StatusRinging:
                          {
                                       // Incoming call comes. 
                                       // add action 
                          }
         }
