Bearer-Independent Call Control
R R Knight, S. E. Norreys, J. R. Harrison · Institution of Engineering and Technology eBooks · 2001
This chapter has given a comprehensive introduction to how the bearer-independent call control offers a complete network solution to provide fully all of the existing PSTN/ISDN services into networks utilising technologies other than circuit switched. While there has been considerable work on SIP to try to emulate PSTN/ ISDN services, BICC offers an immediate solution to public network operators with a large customer base. A further advantage of BICC could be that it will enable SIP to develop independently of the current circuit-switched services, and therefore more efficiently provide exciting new communications possibilities without being restricted by legacy technology and services.
