CELP codingcode excited linear predictive (CELP) coding, which corresponds to standardfed_STD 1016, is an extension of LPC coding. However, as the underlying technologies andmarkets evolve, it is important to consider the effects of these changes on policies and to plan forchange within the policy-making process. Cost components Costs with circuit-switchednetworks Costs with next-generation networkcarriage of voice calls Strong distance dependent18strong dependence on call durationweak distance sip home dependentweak dependence on call durationaccess costs Relatively low fixed cost per basictelephone line (assuminginfrastructure access pipe isavailable)Same as for circuit-switched (assumingbroadband access is not required)Customer support Staff intensive, so high cost or lowlevel of supportautomated, so higher level of customersupport for the cost of providing customersupport on a circuit-switched networkthe Essential Report on IP Telephony52 General economic implications of IP telephonytable 2 – Cost structures (end)From the above table we can see that: Registrar, Proxy, and Redirect. As the EU andfcc determined, if IP telephony technology improves to seriously challenge traditionaltelephone service, then a country can always revisit the question. . The next-generation network operators sip home need to think about how they will recover the cost ofmeeting the data traffic growth generated by their customers. Experience is provided in: Well known programmesinclude the following: Toquantify the transmission delay over the network with any reliability is virtually impossible, in view ofthe great number of unknown factors (routing table, congestion, failures, queuing, …). The reservation of resources is intrinsicallyinequitable, favouring certain flows and certain receivers over others. It allows clecs to offer a wider range of value-addedservices than conventional networks.

The Serverprocesses the request and responds to the client. It is used by both SIP sip home and H. This is usually a policy-based decision taken by therouter. Traffic Conditioning Agreements (tcas) are derived from these slas.
