[question]about the Features of Asterisk


#1

a lot of features of Asterisk are listed on Voip-info.org. Some of them I can not undersand and did not find useful information in Voip-info.org. I paste the features here, and I will paste more if I encouter another features that I can not unterstand. The answered features will be changed to green color.

1.[color=green]Flexible Extension Logic[/color]
2.[color=green]Interactive Directory Listing[/color]
3 [color=green]is “Local and Remote Call Agents” and “Direct Inward System
Access” the same thing?[/color]
4.Privacy


#2

This applies to the idea that within Asterisk that each extension is entirely programmable. Meaning that when you make a call to/within Asterisk, you go through a ‘dialplan’/script which matches the extension and then allows you to invoke features/logic within that script on how that extension behaves.

The ability to have dial by directory capabilities. Where Asterisk has the ability to allow you to enter in a person’s name via DTMF and then dial. This command:

[quote=“bxjy”]3 is “Local and Remote Call Agents” and “Direct Inward System
Access” the same thing?[/quote]

Direct Inward Dial Access is a DID:

en.wikipedia.org/wiki/Directed_inward_dial

Versus local/remote agents is the ability to have the agents on your network or on a remote network (ie - office workers vs home workers).

Broad statement on this one, would need more context.

from web:

Do you mean Direct Inward Dial Access=Direct Inward System Access?
I can not understand why DISA is a DID, can you explain more.

My original post was wrong on this point, I read to quickly and thought I saw ‘Direct Inward Dialing’ not Direct Internal System Access. Here are the details on the command to do this:

It is not the same, please see above.


#5

so can I say : DISA as a command of asterisk realizes the function of “Local and Remote Call Agents”?


#6

The two are unrelated. DISA may be used for calling card applications, for example. Where you want to provide a ‘dialtone’ to someone that calls into the system.

Whereas local/remote agents are users of the system in terms of SIP/IAX2/H323 endpoints, etc.
