I'm using a Babytel trunk and cant seem to set the From: User Part to anything but AuthID (or blank custom field) or else I can't make outbound calls. I don't want to send my authID as callerID, I want the actual trunk # as callerID. Like I can set it to a blank custom field and calls go through as "Unknown". Or I can set it to AuthID, which shows my SIP User ID (which is not my Trunk #). How do I get it to show Trunk # or nothing at all (Instead of Unknown).
