Dear WebMaster,

I have a question: Every body knows that a phone exchange is used for switching the calls. And there is two way to make phone switching: spatial and temporal switching.

Now, in the world of IP Telephony.

  1. Where is the switch?
  2. How is made the switching?
  3. What are the standards supporting this kind of switching?
  4. How are the PTT carries doing IP telephony switching?

I have my own opinion and I would like to know if I am in the right way.

  1. The switch is the Gatekeeper, who makes the routing, generates the information for the billing, and so on.
  2. The switching is made by the filtering of the IP datagrams, that are broadcasting in the respective network.

Thanks for your reply,
Carlos Alcocer.
