How to show Caller ID for Incoming calls on analog line

Hi all,

I need to know how to configure Asterisk to show the incoming Caller ID for an analog call.

In my DialPlan I use the following extension to show it:

exten => s,n,NoOp(CALLER ID is ${CALLERID(all)})

But the CLI output is empty:

Executing [s@IncomingCall:7] NoOp(“DAHDI/1-1”, “CALLER ID is “” <>”) in new stack

Maybe I need some configuration tricks… :wink:

Read chan_dahdi.conf.sample, consult the documentation for the caller ID service provided by your phone company, and set the parameters to match. You may have to subscribe to a caller ID service. You may have to change phone companies before you can do this.
