LAB 1: Using Lines and IP Bandwidth Calculation

It can be used to estimate the bandwidth required through an IP based network for a fixed number of voice paths. voip bandwidth calculator calculates the bandwidth requirements for voice over IP. This depends on the voice compression scheme used (e.g. G.711, G.723, G.728, G.729), the packet interval and the transport protocol (RTP, cRTP).

LAB 2: Erlangs to VoIP Bandwidth Calculation

The Erlangs and Bandwidth Calculator can be used to estimate the bandwidth which must be provided through an IP based to satisfactorily transport a given busy hour traffic level.

Feedback from Students attending this course:

The 4-day course was technically excellent. The architecture of PSTN network and how it works, was very useful to me. I think the instructor is very knowledgeable. He is an excellent instructor. I will recommend this course.

L. Wing, Covad Communications, Covad's Location

In the time we provided I learned much of the terminology and a good basic understanding of how VoIP works. I really appreciated the instructor's knowledge and his willingness to share and enable us to learn.

The instructor is a very knowledgeable and interesting instructor. He works to share knowledge and he's willing to provide information even after class and on breaks. It was a pleasure observing his methods of instruction and being exposed the basics of this complicated subject. Thanks for doing a good job despite not enough time and a too diverse audience.
