Voice over quantum IP

2000 Canadian Conference on Electrical and Computer Engineering. Conference Proceedings. Navigating to a New Era (Cat. No.00TH8492), 2002
There are growing interests to provide telephone services over the Internet. In particular, Internet services providers (ISPs) may become the next generation telephone company especially in providing international telephone services. This paper proposes a novel method called quantum IP (QIP) for transporting international voice traffic over the ...

Voice over IP over satellite links

ICECS 2001. 8th IEEE International Conference on Electronics, Circuits and Systems (Cat. No.01EX483), 2002
Voice over IP (VoIP) services have recently emerged as a low-cost alternative to Public Switched Telephone Network (PSTN) voice service, and as an attractive solution for voice/data integration in public and private networks. Satellite links already have an increasing portion of their capacities used to carry data packets. Convergence of voice and data
