Parameter Description
SBC Signaling
'PRACK Mode'
sbc-prack-mode
[IpProfile_SbcPrackMode]
Defines the device's handling of SIP PRACK messages
for the SIP entity associated with the IP Profile.
■ [1] Optional = PRACK is optional. If required, the
device performs the PRACK process on behalf of the
SIP entity.
■ [2] Mandatory = PRACK is required for this SIP entity.
Calls from endpoints that do not support PRACK are
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
header.
Note:
■ The parameter affects only the initial INVITE request.
■ The corresponding global parameter is
SBCAssertIdentity.
'Diversion Header Mode'
sbc-diversion-mode
[IpProfile_SBCDiversionMode]
Defines the device’s handling of the SIP Diversion header
for the SIP entity associated with the IP Profile.
■ [0] As Is = (Default) Diversion header is not handled.
■ [1] Add = History-Info header is converted to a
Diversion header.
■ [2] Remove = Removes the Diversion header and the
conversion to the History-Info header depends on the
SBCHistoryInfoMode parameter.
For more information on interworking of the History-Info
and Diversion headers, see Interworking SIP Diversion and
History-Info Headers.

URI type (e.g., "tel:") to use in the header, using the
