Parameter Description
■ [2] Mandatory = PRACK is required for this SIP entity.

rejected. Calls destined to these endpoints are also
required to support PRACK.
■ [3] Transparent = (Default) The device does not
intervene with the PRACK process and forwards the
request as is.
'P-Asserted-Identity Header
Mode'
sbc-assert-identity
[IpProfile_SBCAssertIdentity]
Defines the device's handling of the SIP P-Asserted-
Identity header for the SIP entity associated with the IP
Profile. This header indicates how the outgoing SIP
message asserts identity.
■ [0] As Is = (Default) P-Asserted Identity header is not
affected and the device uses the same P-Asserted-
Identity header (if present) in the incoming message for
the outgoing message.
■ [1] Add = Adds a P-Asserted-Identity header. The
header's values are taken from the source URL.
■ [2] Remove = Removes the P-Asserted-Identity

SBCAssertIdentity.
