Description
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.
