Abstract
A system and method of ring back notification for the EP phone is provided. A caller and a receiver communicate in the IP network through the respective connected nodes. When the receiver'"'"'s network is busy, a request message is sent to the server of the IP network. The server receives the request message of starting a ring back notification and sets a ring back notification tag. Afterwards, the network status of the receiver is detected recurrently. Once the receiver'"'"'s network is detected to be idle, the ring back notification is sent to the server and then to the caller'"'"'s node. The function of the ring back notification is to notify the caller that the receiver'"'"'s network is idle after the receiver'"'"'s busy status is over, so that the caller can communicate with the receiver in time.
