1.Flexible Extension Logic

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.

2.Interactive Directory Listing

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:

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.

you said:

Direct Inward Dial Access is a DID

voip-info says:

DISA (Direct Inward System Access) Allows someone from outside the telephone switch (PBX) to obtain an “internal” system dialtone and to place calls from it as if they were placing a call from within the switch. A user calls a number that connects to the DISA application and is given dialtone and context.

from web:

Direct Inward Dialing (DID, also called DDI in Europe) is a feature offered by telephone companies for use with their customers’ PBX system, whereby the telephone company (telco) allocates a range of numbers all connected to their customer’s PBX.

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.

[bxjy]

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

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.
