  3. IP Telephony : Definitions • IP is an acronym for Internet Protocol. It is a communications Protocol developed to support a packet switched network. • IP Telephony is the exchange of information primarily in the form of speech that utilises a mechanism known as Internet Protocol. • Internet Telephony: the combination of the term « Internet » with the term « telephony » is seen as inappropriate. The Internet offers many capabilities to users including the ability to carry bi-directional speech in real time or near real time. This is considered to be an intrinsic capability of the Internet and not a telecommunications service. ANRT, March 1, 2005

  9. IP Telephony : Impact IP telephony has brought about a major paradigm shift in the business of telecommunications and is impacting the communication process in an all-encompassing maner. ANRT, March 1, 2005

  10. Prices: impact ANRT, March 1, 2005

  11. Telephony IP: the Benchmark ANRT, March 1, 2005

  12. Moroccan case • Public IP Telephony • Technologic Neutrality: public telephony is subjected to the mode of licences whatever technology used; • Private IP Telephony • To carry speech is authorized within independant network (authorizations’ mode) ANRT, March 1, 2005

  13. Moroccan case • IP Telephony service isn’t offered by the incumbent operator (accounting rate); • IP Telephony service exists in moroccan companies; • Some ISP provide this service illegally : ANRT proceeds to control and conducts inquiries; • IP equipment type approval deposit : Why? ANRT, March 1, 2005

  14. Moroccan case • Manage fraud in IP international traffic; • Follow-up current standardization work at international authorities level; • Propose the transfer of DNS management to an independent of operator entity. ANRT, March 1, 2005

  15. Moroccan caserole of ANRT • Direct intervention • Inquiries (article 24 of the law n°24-96) • Publication of a decision about IP statute (decision ANRT N°04/04 of April 6, 2004)see web site adress : www.anrt.net.ma. • Indirect intervention • Lower prices; • Competition setup.
