VoIP is a technology that allows phone calls to be made over the internet. It works by converting analog voice signals to digital data that is sent in packets over IP networks. Common VoIP technologies include H.323, SIP, and RTP. VoIP can be implemented through analog telephone adapters, IP phones, or computer-to-computer calls. While VoIP provides benefits like low costs and integration with other applications, it also faces challenges related to quality of service, emergency calls, and lack of redundancy in case of power failures.

10. Disadvantages of VoIPINTRODUCTIONVoice over Internet Protocol (VoIP) is a transmission technology for delivery of voice communications over IP networks.

11. Internet telephone call are conversion of the analog voice signal to digital format and compression/translation of the signal into Internet protocol packets.

12. VoIP systems employ session control protocols to control the set-up and tear-down of calls as well as audio codecs.

13. With VoIP, we can make a call from anywhere we have broadband connectivity.VoIP Overlay Routing SchemeOverlay Network ArchitectureA VoIP overlay network (VoON) consists of VoIP endpoints, edge nodes and relay nodesIntegration into Call SignalingSignaling phase can be used by a VoON to determine the most suitable path for the media streams of a call. Measurements-- The quality of service on candidate routes needs to be determined at the time a routing decision is made --The quality of a call in progress needs to be monitored.
