I have allready downloaded the book, and read it. But the technical language makes it extremly hard to get an in depth understanding of VOIP, and the whole asterisk.
There are so many different things to consider. DID, SIP, VOIP and this goes on and on. And when not fluent in english this is hard to grasp. I can communicate oraly in english after years of practicing, but techincal english like this is hard for me.
So, lets assume this:
I have asterisk running on a server., ready to configure.
I do have a broadband connection also.
All my inhouse telephones are two or some years old PSTN, connected with plain telephone cables.
What will I need to look for (sign up for) to be able to make asterisk work, so that I can make phonecalls from the old phone handset, and the calls get transferred via the broadband connection, rather then the telecoms wires.?
Can someone try to explain the difference between DID,VOIP, SIP and others I should be aware of?
What is the bare minimum I would need to setup asterisk? Once again I do not think of hardware or the asterisk server itself, but more what type of subscription/service I need to sign up for in order to make things work.
If needed I will explain even further.
