Technical regulation also involves specification of"Quality of Service" on each of the technical interfaces, such as UNI and NNI, so that end-to-endquality of service can be guaranteed to the customers in a multi-operator environment. ATM layers,pc to pc phone call
AAL3/4 oraal5). Information for the sender . The RTP protocol by itself does pc to pc phone call
not provide any usefulinformation to the sender. 4 and 4. Audio, video, etc.
Another idea is to migrate the core network of the network transport technology on to a packettransport for voice services which can go gradually without jeopardizing existing investments. However, in networks containing gatekeepers, the initial sip gateway admissionmessage can take place between the calling endpoint and the gatekeeper, using thegatekeeper’s RAS channel Transport Address. Session Initiation protocolsession Initiation Protocol or SIP is the IETF standard for voice or multimedia sessionestablishment over the Internet. This is done in pc to pc phone call alimited manner in H. Measurement descriptionservice Availability The availability of the pc to pc phone call users’ network connection and depends onthe connected network sip relay device. All forms of IP telephony operations are permittedincluding PC-to-PC, PC-to-Phone and Phone-to-Phone. A longer and less congested path maybe better for qos-demanding pc to pc phone call
traffic as compared to the shortest, highly congested path. The Essential Report on IP Telephony68 Conclusions to Part III: The ubiquitous multimedia terminal, whosecurrent avatars are the multimedia desktops, wireless handsets, and Internet- enabled tvs,are increasingly being seen as the indispensable tool to conduct business and socialengagements. The case of accessing to the Internet through an ISP is cited here as thedominant example. Theinternet offers many capabilities to users including the ability to carry bi-directional speech in realtime or near real time. Thenetwork interconnections are therefore not pre-established, and must be implemented on a case-bycasebasis by means of gateways or bridges of varying complexity. Today,with coding systems using the analysis-synthesis technique, these being the most efficient systems forthe application of IP telephony, great progress is being made toward guaranteeing quality of servicefor this type of application over IP networks. 1 in Annex A describes the IP protocol and Section A. This two-step strategy is illustrated hereafter for trunking and access. 1 Security in the context of the telephone networkas we have already seen (see the chapter on network architecture), one of the main differencesbetween the telephone network and IP networks lies in the concentration of intelligence pc to pc phone call and inprocessing within the network at the level of switching nodes.
. Where confidentiality is concerned, the telephone network provides full confidentiality that islimited solely by the legislation in force (tapping of a telephone line by the nationalauthorities).
