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 draft-ietf-sipping-update-pai-00. This feature is always enabled.

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.

•Support signals 0-9, #, *
