DOD Number – Include the trunk's DOD number in the PPI
Header. If no DOD number has been set, the trunk's preferred

If enabled, the SIP INVITE message sent to the trunk will contain PAI (P-
Asserted-Identity) header including configured PAI Header. The default
setting is "No".
Note: "Send PPI Header" and "Send PAI Header" cannot be enabled at
the same time. Only one of the two headers are allowed to be contained
in the SIP INVITE message.
If "Send PAI Header" is enabled and "PAI Header" is configured as
"123456" for instance, the PAI header in the SIP message sent from the
UCM will contain "123456". If "Send PAI Header" is enabled and "PAI
Header" is configured as "empty", the PAI header in the SIP message sent
from the UCM will contain the original CID.
Note: "Send PAI Header" needs to be enabled in order to use this feature.
Only alphanumeric characters are allowed and/or special characters #*-
_+. with a limit of 64 characters.
If enabled and "From User" is configured, the INVITE's From header will
contain the DOD number.
If checked and option "Send PAI Header" not checked, the PAI header will
be passthrough from one side to the other side.
