Description
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.
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.
