the operations of registration,admission and status request to the gatekeeper. Mary and John can then directly communicate over the IP network and RTP/UDP protocol. Especially given the possibility of long distance savings, voip can boost consumer demandfor local telephone service. The question ofallowing Internet telephony is distinct from the question of whether providers ofinternet telephony service should be required to pay universal service charges. On the one hand it offers cheaperprices and lower costs, but it may also undermine the pricing structure of the incumbentpublic telecommunication operator. . An originating circuit-switched network operator usually charges the user to make a call andthen pays another fixed circuit-switched network operator to terminate it. Such arrangements are still relatively rare and many Internet exchanges only allow settlement-freepeering. Oftel also has powers to imposestandards for Quality of Service (qos), but again has refrained from doing so in the case ofvoip, on the ground that, in competitive markets, there may be a demand for cheaper servicesthat offer lower quality. These networks possessed characteristics that satisfied the peculiar get high lyric n sip requirements of theservice they provided. This trend is principally the result ofincreased competition and pressure from countries that make net settlements. For ITU Sector Members that are equipment vendors, the development of new IP-basedproduct lines may be essential to future growth and profitability. Potential policy implications of enumstudy Group 2 of ITU's Telecommunication Standardization Sector is currently addressing principlesand procedures for the administration of electronic numbering (ENUM) as well as defining aframework for the possible role of ITU.

The upshotof this is that, in some developed countries, the volume of data traffic over telephone networksexceeds that of the voice traffic for which those networks were originally designed7. This situation does not arise in the case ofnational land connections using circuit switching free provider voip between two parties, since here the delays aresufficiently short. Thevpn provider sets up, by specially engineering the signalling arrangement on top of the Internet, avirtual network that ensures acceptable quality-of-service properties among all of the company's11 Actually, it is more proper here to use the term Service Level Specification (SLS) rather than SLA, the former being thetechnical specification of the latter which can be considered as the legally binding agreement.
