i'm connected with an E1 PRI with 4 digits (eg: 4564XXXX) and i'm able to do external calls. My problem is that when ax external phone receives the call, it sees on the display only the PRI number 4564 and not the complete number (PRI + internal DN).
I read the manual try to make it displayed changing these settings:
Call Routing Information - Outbound Calls (on the device menù of PRI card) ----> Calling Party Presentation (enabled) and Calling Party Selection (originator)
but it doesn't work.
I'd like to know if these are the corrects settings or if i must change these in other menu also (eg: route pattern, ecc...)
