Systems and methods for handling an incoming telephone call received at a private branch exchange system and directed to an employee enable an actual or virtual receptionist to camp the call on the employee's extension. When the call is camped on the employee's extension, the private branch exchange system causes a push notification to be sent to a telephony device used by the employee to notify the employee that a call is camped on his extension. Such a push notification may also inform the employee about how many calls are camped on his extension. Further, such a push notification may provide the employee with information about the identity of a calling party whose call is camped on the employee's extension.
