Talk:Automatic number identification

From Wikipedia, the free encyclopedia

[edit] Block

If anyone has a verifiable source that indicates whether the type of caller anonymity generally provided to certain civil servants such as district attorneys and public defenders is just caller-id blocking, or whether it prevents ANI identification as well, please add it to the article. --Elvey 23:37, 21 February 2007 (UTC)

I called one of the credit reporting agencies toll-free numbers from such a line and they were able to tell I was calling from California. So these lines just have Caller-ID blocking. --69.12.142.18 23:57, 28 February 2007 (UTC)

[edit] ANAC disagreement

I support the includer on this one. Early in my career when I was wiring the OSL in 5XB Switch for Automatic number announcement circuit, it was MFANI. Nowadays of course it's different but let's have a little ancient history. Jim.henderson (talk) 02:21, 1 April 2008 (UTC)

Point taken (on ANA) but I think the diatribe into secrecy, payphones, and criminal activity is a bit much. Bellhead (talk) 21:01, 6 April 2008 (UTC)

[edit] Spoofing

It's actually very easy to spoof the ANI. My company uses an Envox IVR based phone system to do quality control testing on restaruants, pizza joints, etc all over the US. We spoof every outbound call to appear to be a local call to the places. It's a standard feature in the software where you just tell it to set the ANI to whatever you want. —Preceding unsigned comment added by 209.11.231.66 (talk) 13:38, 28 May 2008 (UTC)
