It would be nice to be in Sydney or Melbourne to have cable wouldn't it, but there are millions of people who don't have access to it including me. I'm sorry to say but copper still dominates overall for use in homes and businesses Australia wide. Every business and home has something whats called a main distribution frame or MDF. homes are fed via a 2pr copper cable usually and businesses usually have a 10pr,30pr, 50pr or a 100pr copper lead in cable. Most PABX's and PBX use either a PSTN or ISDN service which is through the use of copper and backbone through optic fibre or straight fibre in some instances. Most data for businesses and the home Australia wide is still used through broadband or straight DSL connections. Larger businesses tend to rely on multiple ADSL connections through load balancing routers. Cable isn't available to most Australians ;)
Oh, and any calls I receive that have that delay, I simply hang up because it's always some bastard overseas trying to sell me something. Voip calls on average depending on what codec is used only uses around 60Kbps of bandwidth, which is sweet **** all, set up correctly it sounds good. Too many noobs don't set it up right.
