SipLineCapacityReached
Whenever the telephony engine detects a new incoming phone call and there are no more phone lines available, the SipLineCapacityReached event is sent to application software. This event allows unattended IVR applications to detect when all phone lines are consumed. Monitoring this event in your application software will allow you to determine if you have enough phone lines to service your particular application.
