Press the remote communication with the "IP Phone"


Unlike our values. communication costs in Japan this time of year in 90 years of age, if the cost per call of 3 minutes was 10 yen, so that the time of long distance calls just 7.5 yen per three minutes for calls International Thefore until 2001. For calls from Japan to Indonesia, about seven minutes, costs about 1000 yen, 1000 yen, but now we can have a conversation Japan - Indonesia for 120 minutes.
There are many factors that cause costs. Communication in Japan is more expensive. The only role of government itself. The telecommunications giant NTT to order on line monopoly this order is issued after the strangulation Japanese experience in the development of broadband technology, ADSL (Asymmetric Digital Subscriber Line) broadband technology in Japan until 2001. Range and the neighboring South Korea in 2001, the number of ADSL users in ginseng to 1.5 million in 8000, although it is not just Japan's NTT offer the opportunity to Thep. menggunakancooper ADSL to maintain activity with an ISDN connection to the Internet, at the opening of a place in this line of NTT Cooper, appearing like mushrooms growing provider of ADSL broadband services connected with low cost and with minimum a 5. Mbps (ADSL speeds up to 50Mbps current example).
The rapid development of ADSL technology enables the development of IT in Japan soon. The variety of services in broadband network access, which occur, particularly in the VoIP (Voice over IP), in which the source IP telephony and Internet Protocol communications. As for the development of ADSL before the development of IP phones are not smooth as expected. Because of the challenges posed by NTT contrast with the implementation of IP - service companies will work to NTT Communications is possible during the month of March 2003 IP Phone provides voice communication officer in Japan, providing a range of specific IP numbers. with the prefix 050 phonepelanggan broadband giant Yahoo (Yahoo BB) and before the merger IP phone in Japan in 2002 on charges of using Yahoo BB to let long-distance rates for local and durable slate. 7.5 yen per three minutes.
Notice different sounds to use copper telephone lines. (Fixed) IP Phone uses the Internet as a medium. voice communications from one place to another linememelukan. The negotiations between operators using the same operation interface for operators of liquor and final destination. Operators of long distance communication link more. This is what is needed. Communication becomes expensive. When low (internal communication) and costs less. Rather, the use of distance (great moment for international communication), so the cost increase. Phonesama the other with voice communications over IP are independent of the operators mentioned above. Why the media is a network. Internet. While we are connected. Internet, we can communicate without worrying about the cost of communication that are overloaded.
The IP phone has two aspects of communication such as Internet Phone danIP phone. If the data in the form of sound, in the form of packets sent over the Internet, called Internet Phone If the voice packets are sent. Special Internet Network ISP (Internet Service Provider, ed.), Then this is called IP phone real.
Thep things taken by your IP Phone is a matter of sound quality. The Internet and Mobile IP Phonesama together through the Internet would be seriously affected by traffic conditions (traffic) on the Internet, and when trafficinternet. Time, space and better sound. But beyond the sound quality. incompatible with the sound quality of IP phone license ITU (International Telecommunication Union) should be Delaydan MOS value (average of observations) of at least 4.0 and delay time (delay time) for 100 ms.
