Can I make calls over the Internet, with a dedicated line?

So ... there is a leased line ... whether as a call through, I do not have a normal city phone?

The name - IP-telephony :blink:

Should your provider offers this service - it can be.Even on the dial. smile.:rolleyes:

His demand and the price for this service, as well as requirements for the software. (Usually it is necessary to support G.729)

There is a great program Skype, which offers calls at cheaper rate than any Internet Phone.
