The SIP stack: A look under the hood of Voice over IP

Dr. Vijay K. Gurbani

Thursday February 22nd 2018 at 6:30pm
Fountaindale Library Bolingbrook IL, Board Room (2nd floor)


If you are at all curious about the technology behind voice over ip which has almost completely replaced the old wired telephone infrastructure you will not want to miss this presentation and discussion hosted by Dr. Vijay K. Gurbani, you will find out the details of exactly how this signalling and call setup protocol for IP-based communications puts voice communications on the internet. You will learn about how this technology was developed, the network protocols and elements that make it work and the messaging that facilitates and replaces the mechanical signalling of the old wired network. You will learn about what's required in a network and how it has to scale to make this work in a large corporate environment. You will have the opportunity to ask questions and learn about other aspects of this as well.

As usual we will be having a "Meeting After the Meeting" for talk and drinks, and since the meeting is on Thursday we are planning it at the Bulldog Alehouse restaurant in Bolingbrook on Weber Rd. The link goes to the restaurant's Bolingbrook website with a clickable, expandable map.
