Delivering Incoming Calls to the Auto Attendant

Any call coming into the system will enter the dialplan in the context defined for what-

ever channel the call arrives on. In many cases this will be a context named incoming,

or from-pstn, or something similar. The calls will arrive either with an extension (as

would be the case with a DID) or without one (which would be the case with a tradi-

tional analog line).

Whatever the name of the context, and whatever the name of the extension, you will

want to send each incoming call to the menu. Here are a few examples:

[from-pstn] ; an analog line that has context=from-pstn (typically a DAHDI channel)

exten => s,1,Goto(main_menu,s,1)

[incoming] ; a DID coming in on a channel with context=incoming (PRI, SIP, or IAX)

exten => 4169671111,1,Goto(main_menu,s,1)

Depending on how you configure your incoming channels, you will generally want to

use the Goto() application if you want to send the call to an auto attendant. This is far

neater than just coding everything in the incoming context.
