Parameter Description
SBC Registration Timers
SBC User Registration Time
[SBCUserRegistrationTime]
Defines the duration of the periodic registrations between the
user and the SBC (SBC responds with this value to user).
When set to 0, the SBC does not change the Expires value
received in the user’s REGISTER request. If no Expires
header is received in the REGISTER and
SBCUserRegistrationTime = 0, the Expires value is set to
180 seconds (by default).
The valid range is 0 to 2,000,000 seconds. The default is 0.
SBC Proxy Registration Time
[SBCProxyRegistrationTime]
Defines the duration for which the user is registered in the
proxy database (after the device forwarded the REGISTER).
When set to 0, the SBC sends the Expires value as received
from the user to the proxy.
The valid range is 0 to 2,000,000 seconds. The default is 0.
SBC Survivability Registration Time
[SBCSurvivabilityRegistrationTime]
Defines the duration of the periodic registrations between the
user and SBC, when the SBC is in survivability state (i.e.,
when REGISTER requests cannot be forwarded to the
proxy, and is terminated by the SBC). When set to 0, the
SBC uses the value of the parameter
SBCUserRegistrationTime for the SBC response.
The valid range is 0 to 2,000,000 seconds. The default is 0.
