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.
Defines the registration time (in seconds) that the device includes in
register responses, in response to SIP REGISTER requests from
users belonging to the SIP entity associated with the IP Profile.
The parameter applies only to users that are located behind NAT and
whose communication type is UDP. 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, unless the user sends a refresh REGISTER before the
timeout. Upon timeout, the device removes the user's details from the
registration database, and the user will not be able to make or receive
calls through the device.
The valid value is 0 to 2,000,000. If configured to 0, the Expires
header's value received in the user's REGISTER request remains
unchanged. By default, no value is defined (-1).
Note: If the parameter is not configured, the registration time is
according to the global parameter SBCUserRegistrationTime or IP
Profile parameter IpProfile_SBCUserRegistrationTime.
Defines the registration time (in seconds) that the device includes in
register responses, in response to SIP REGISTER requests from
users belonging to the SIP entity associated with the IP Profile.
The parameter applies only to users that are located behind NAT and
whose communication type is TCP. The registration time is inserted in
