Summary:                    PrivacyManager not detecting anonymous SIP calls
Description: 
PrivacyManager is not detecting anonymous calls that come in on the SIP
channel. Whenever anonymous calls come in on this channel, the CLI message
"CallerID Present: Skipping" shows up and and my SIP phone simply rings
anyway.

I'm reporting this as a bug because I suspect that the cause is due to the
fact that when there is no CID, the results are not always the same. For
example, I see in my CDR database that when anonymous calls come in via the
SIP channel, the clid field shows:

                 "Anonymous" <anonymous>

However, when anonymous calls came in though my old ISDN line (which I
can't test anymore because it no longer exists), the clid field would
show:

                 CID withheld

Although I'm not sure, I suspect that PrivacyManager may recognize the
latter format, but not the former.

This is working as intended.

The "problem" is that the provider is adding a Caller ID number (of
"anonymous"), thus avoiding the check in app_privacy.  If you don't want
this behavior, you can check in the dialplan if the CID number is
"anonymous" and set it to be empty before calling app_privacy. 
Alternatively, you could ask the provider to stop setting the Caller ID
before sending the call to you.
