I am using FXO ports. My confugration is like:
connection plar 1100
This 1100 is a AutoAttendant which will be routed to variuos users depending on the DTMF inputs. Say "pressing 1" will enable to dial by extension. If the call is routed to the an extension, the caller id is shown as " Unknown number" in that Phone instead of the actual external number.
How can I make to display the actual caller ID in this case ?
