Dale,
Suppose you are building a sip adapter for black phones. (Well, black
phones with a callerid display.)
What criteria should it use before displaying the callerid of the
incoming call?
It is restricted by hardware and convention regarding what it displays -
generally just digits for the number. The customer is going to be upset
if he just replaced a pstn phone, and isn't getting callerid from the
same callers he used to get it from. OTOH, the phone is likely to be
worried about trusting From - its just too easy to forge.
