asterisk users - Dec 2010 - Asterisk as a caller ID

In a 1.4.24 system, out of several lines, one of ours gets 1 or more random
calls a day with "Asterisk" as the caller ID.

I have just seen this described in the last couple of weeks, but at the time
it wasn't happening to us, and I the explanation didn't stick with me.

Can anyone give me a pointer to this "feature"?  Searching the message
base
for "Asterisk" seems futile.

Thanks!

In my experience, it happens when the caller is blocking their CID.  I 
have programming in place that assigns the named restricted and the 
phone number of 0 if the caller-id is blank:

exten => s,1,GotoIf($["${CALLERID(num)}" = "" ]?2:3)
exten => s,n,Set(CALLERID(all)=Restricted <0>)
