|
| SBC Registration Timers |
|
|
| SBC User Registration Time | Defines the duration of the periodic registrations between the |
|
| [SBCUserRegistrationTime] | 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 | Defines the duration for which the user is registered in the |
|
| [SBCProxyRegistrationTime] | 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 | Defines the duration of the periodic registrations between the |
|
| [SBCSurvivabilityRegistrationTime] | 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. |
