without interference.
■ [1] Handle always = Handle fax according to fax
settings in the IP Profile for all offer-answer

Profile.
■ [0] All coders = (Default) Use only (and all) the coders
of the selected Coder Group configured using the
SBCFaxCodersGroupID parameter.
■ [1] Single coder = Use only one coder. If a coder in the

in the SBCFaxCodersGroupID, the device uses this

coder listed in the Coders Group ID
(SBCFaxCodersGroupID).

incoming offer coders (from the calling "fax") and the
coders of the selected Coder Group (configured using
the SBCFaxCodersGroupID parameter).

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 Coder Group
(SBCFaxCodersGroupID, then the device uses this
coder. If no match exists, the device uses the first
listed coder of the matched coders between the
incoming offer coders (from the calling "fax") and the
coders of the selected Coder Group.
Note: The parameter is applicable only if you set the
IpProfile_SBCFaxBehavior parameter to a value other than
