Configurable SIP P-Asserted Identity (PAI)

The IP Phones support a private extension to SIP for Asserted Identity within
trusted networks (as defined in RFC 3325). This feature allows a network of
trusted SIP servers to assert the identity of authenticated users, and verify that
phone messages originate from a Trusted Identity. Upon receiving a message from
a caller in the Trusted Network, the IP phone reads the contents of the
P-Asserted-Identity (PAI) header field and displays it on the phone UI.
The phones provide the ability for the Administrator to enable or disable the
display of P-Asserted Identity (PAI) information on the phone using the following
parameter in the configuration files:
• sip pai
Enabling/Disabling P-Asserted Identity (PAI)
