To compound the problem, carriers are slow to update their ANI lists, so if you make a change to the CLID associated with a toll free number, it can take several months to propagate, and in many cases has to be done at the carrier level.
For instance, my previous employer had a PBX which allowed you to modify the CLID, but if you wanted the PRI to pick up the CLID, you also had to make the change with the carrier. For the original poster, if you haven't seen this yet, check out http://en.wikipedia.org/wiki/Automatic_number_announcement_circuit, and then check what the difference is between caller id, and ANI.

What you may want is an ANAC number which tells you the phone number for a particular line. http://en.wikipedia.org/wiki/Automatic_number_announcement_circuit -----Original Message----- From: Klint Price [mailto:[email protected]] Sent: Wednesday, September 16, 2009 9:46 AM To: NT System Admin Issues Subject: RE: Phone number to tell you your phone number. That may work for POTS lines, but is not as reliable if calling from a PBX, or a line that is tied to a toll free number. You can't even rely on the number written on the wall jack at the DMARC (as I found out yesterday). If you happen to know a field technician at the local telecom, they have access to other tools: http://www.docdroppers.org/wiki/index.php?title=Qwest_Field_Accessed_Service_Tools or you could always http://www.ehow.com/how_941_determine-telephones-telephone.html Klint -----Original Message----- From: Angus Scott-Fleming [mailto:[email protected]] Sent: Tuesday, September 15, 2009 10:43 AM To: NT System Admin Issues Subject: Re: Phone number to tell you your phone number.
