But this section 8 is written so generically (eg "However, any specific behavior is specific to implementations or services") that it is pretty much saying nothing on the usage of From header vs P-Asserted-ID. On a feature as simple as which header to use for caller ID display, so one carrier can try to enforce the From header while another could use the P-Asserted-ID? Is there no standard pertaining to SIP in IETF and ITU which clarifies the proper usage?
