Voice Over IP

VoIP IN THE INTERNET AND IN PRIVATE INTERNETS

From a technical standpoint, the deployment of synchronous traffic over a private internet offers the same challenges as just described for the public Internet.

However, there is one big difference between IP telephony in a public Internet and a private intranet: An internet can be made to be much more "cooperative" than the Internet. Private networks can be more readily tuned than the public Internet. Therefore, they provide much better support of VoIP than the public Internet, at least for the time being. Eventually, I believe the public Internet will perform well enough to support toll-quality (telephone quality) traffic.
