User's Manual
associated with the IP Profile. This enables the interworking of
the DTMF payload type for RFC 2833 between different SBC call
legs. For example, if two entities require different DTMF payload
types, the SDP offer received by the device from one entity is
forwarded to the destination entity with its payload type replaced
with the configured payload type, and vice versa.
The value range is 0 to 200. The default is 0 (i.e., the device
forwards the received payload type as is).
Assigns a Coders Group to define the supported fax coders for
fax negotiation for the SIP entity associated with the IP Profile.
For configuring Coder Groups, see Configuring Coder Groups on
page 379.
Note: The parameter is applicable only if you set the
IpProfile_SBCFaxBehavior parameter to a value other than [0].
Enables the device to handle fax offer-answer negotiations for
the SIP entity associated with the IP Profile.

[0] As Is = (Default) Device forwards fax transparently,
without interference.

[1] Handle always = Handle fax according to fax settings in
the IP Profile for all offer-answer transactions (including the
initial INVITE).

[2] Handle on re-INVITE = Handle fax according to fax
settings in the IP Profile for all re-INVITE offer-answer
transactions (except for initial INVITE).
Note: The fax settings in the IP Profile include
IpProfile_SBCFaxCodersGroupID, IpProfile_SBCFaxOfferMode,
and IpProfile_SBCFaxAnswerMode.
Defines the coders included in the outgoing SDP offer (sent to
the called "fax") for the SIP entity associated with the IP Profile.

[0] All coders = (Default) Use only (and all) the coders of the
selected Coders Group ID configured using the
SBCFaxCodersGroupID parameter.

[1] Single coder = Use only one coder. If a coder in the
incoming offer (from the calling "fax") matches a coder in the
SBCFaxCodersGroupID, the device uses this coder. If no
match exists, the device uses the first coder listed in the
Coders Group ID (SBCFaxCodersGroupID).
Note: The parameter is applicable only if you set the
IpProfile_SBCFaxBehavior parameter to a value other than [0].
Defines the coders included in the outgoing SDP answer (sent to
the calling "fax") for the SIP entity associated with the IP Profile.

[0] All coders = Use matched coders between the incoming
offer coders (from the calling "fax") and the coders of the
selected Coders Group ID (configured using the
SBCFaxCodersGroupID parameter).

[1] Single coder = (Default) Use only one coder. If the
incoming answer (from the called "fax") includes a coder that
matches a coder match between the incoming offer coders
(from the calling "fax") and the coders of the selected Coders
Group ID (SBCFaxCodersGroupID, then the device uses this
coder. If no match exists, the device uses the first listed coder
