Description
Defines the handling of ISUP data for interworking SIP and
SIP-I endpoints.
■ [0] Transparent = (Default) ISUP data is passed
transparently (as is) between endpoints (SIP-I to SIP-I
calls).
■ [1] Remove = ISUP body is removed from INVITE
messages.
■ [2] Create = ISUP body is added to outgoing INVITE
messages.
■ [3] Create If Not Exists = ISUP body is added to
outgoing INVITE messages if it does not exist in the
incoming leg. If it exists, unknown fields and messages
by the device are passed transparently, while known
fields can be manipulated using Message Manipulation
rules. For known fields, some values that are "reserved
for national use" may be changed to default.
For more information on interworking SIP and SIP-I, see
Interworking SIP and SIP-I
Defines the ISUP variant for interworking SIP and SIP-I
endpoints.
■ [0] itu92 = (Default) ITU 92 variant
■ [1] Spirou = SPIROU (ISUP France)
Defines the maximum duration (in minutes) per SBC call
that is associated with the IP Profile. If the duration is
reached, the device terminates the call.
The valid range is 0 to 35,791, where 0 is unlimited
duration. The default is the value configured for the global
parameter, SBCMaxCallDuration.
Defines the registration time (in seconds) that the device
responds to SIP REGISTER requests from users
belonging to the SIP entity associated with the IP Profile.
The registration time is inserted in the Expires header in the
outgoing response sent to the user.
The Expires header determines the lifespan of the
registration. For example, a value of 3600 means that the
registration will timeout in one hour and at that point, the
user will not be able to make or receive calls.
The valid range is 0 to 2,000,000. The default is 0. If
configured to 0, the Expires header's value received in the
user's REGISTER request remains unchanged. If no
Expires header is received in the REGISTER message and
the parameter is set to 0, the Expires header's value is set
to 180 seconds, by default.
Note: The corresponding global parameter is
SBCUserRegistrationTime.
