P-Asserted-Identity (PAI) Support in UPDATE message
In previous releases, the IP Phones supported P-Asserted-Identity (PAI). In Release 2.3, the
phones now support PAI header in the UPDATE message, according to

If an UPDATE is received with a PAI header from a trusted source, the phone updates the display
with this information. The phone ignores any PAI received from untrusted entities.

requests. The following is now supported:
