There is therefore a trusted single point within the network that can send a "duplicate" of all callswhere this subscriber is involved towards the legal entity that asked for the interception. When sending an INVITE message, the client may use the least precise of the above addresses (say theuser voip pbx at domain one). This coding system, which corresponds to Recommendation G. 114) are given to indicate the classes of quality and interactivity according to the transmission delayin a telephone conversation. 8 – Addressing and numbering plans for telephone services fornative IP subscribersone of the main advantages of the worldwide telephony network is the existence of a universalnumbering scheme for subscribers that is agreed upon internationally under the auspices of ITU. For example, In other terms, how can end-to-end consistency be ensured regarding Quality of Service, security orbilling, to cite the most important issues? To this end regulatory authorities in the European Union willregularly undertake a market analysis review of relevant markets. By offering voip, in and of itself, carrier's can retain customers and increasetraffic. Voice traffic is real-time traffic and if there is too longa delay in voice packet delivery, speech will be unrecognizable. If thecall is being handled voip pbx by a Private Branch Exchange (PBX), the PBX forwards the call tothe destination telephone.

Likewise, the architecture of a telephone network is based on the assumption that it will essentially beused for person-to-person voice communication, this being an advantage in terms of optimization ofthe network for this application, but also a source of weakness if the same network is used for otherapplications (data transfer) where the requirements differ residential voip from those pertaining to voice.
