Re: [asterisk-users] Automatic Number Identification and anonymous calls
2012/2/9, Maximilian Grobecker m.grobec...@portunity.de: Hello, I know about the german phone system that the sense of an anonymous call is, that the called party has no way to get the caller's number in any way. The last switch honours the anonymous bit and removes the phone numbers before sending the call to the called party. In EURO-ISDN you have a feature called CLIRO which means Calling Line Identification Restriction Override and is only availiable to emergency services or special governmental services. With this line feature the last switch ignores the anonymous bit and you can see both caller id and ANI. The US phone system may work in another way, but if I call another person and want to hide my number I would appreciate if my phone number is not sent to the called party in any field. So this issue sounds to me more like feature than a bug ;-) Yes, I agree but what I rate as a bug is asterisk copying CID data into ANI field. The reasoning is asterisk should don't modify, unless explicitely configured to do so, whatever comes from the public network side. For instance, it seems analog lines cannot support ANI. So when receiving a call through an analog line, this ANI field should be simply empty. It seems that today default is to copy CID into ANI field. This is misleading as you may think this ANI is somehow more trustable than CID alone. I agree that if a caller requires anonymity, then, except for very special cases (emergency services, for instance), ANI should also be hidden by the telco.

[asterisk-users] Automatic Number Identification and anonymous calls
Hi, This morning I called an analog line from a cell phone. For the first call, I made a standard call and could both read my CID and ANI in my Asterisk console. For the second call, I choosed to hide my ID and, to my surprise, I read that my CID and ANI were both empty. I always thought that ANI (Automatic Number Identification) could not directly be set or changed by end users. In this experiment, it seems that if an end user calls anonymously, the ANI is also hidden to the receiving party. Is this standard practice ? Does it depends on the telco networks the call is passing through ? Thoughts ? Regards -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
