| Parameter | Presence | Type | Default | Description |
---|
| requireRegistration | O | enumeration | none | This flag should be SUPPORTED when the associated trunk group is used for endpoints optionally requiring registration. It should be REQUIRED in cases where absolutely no unregistered IAD may make any calls. It should be SUPPORTED-GROUP to allow calls from unregistered users and to allow calls from users whose username does not match with the stored URI. It should be REQUIRED-NONPRIORITY when unregistered IAD cannot make any non-priority calls. NONE (default) is selected when no registration validation is to be performed. |
| expires | O | uint16 | 3600 | This is the time (in seconds) a SIP endpoint's registration session lasts before requiring re-registration. The minimum value is 15 seconds but it should typically be much longer. This value does not apply if the endpoint is NAT'd. |
| insideExpiresMinimum | O | uint32 | 3600 | This controls the initial expires value in a REGISTER relayed to a registrar. The max of this value and the value received from the IAD will be used. |
| includeXOriginalAddr | O | enumeration | disabled | Flag that specifies if the X Original Addr header needs to go in REGISTER message. |
| bulkRegisterFormat | O | enumeration | disabled | This flag determines how the registration requests are formatted |
| intRefreshFactorMin | O | uint16 | 0 | This determines internal refresh factor minimum for calculating the internal expire towards the registrar. |
| intRefreshFactorMax | O | uint16 | 0 | This determines internal refresh factor maximum for calculating the internal expire towards the registrar. |
| extRefreshFactorMin | O | uint16 | 0 | This determines external refresh factor minimum for calculating the external expire towards the registrar. |
| extRefreshFactorMax | O | uint16 | 0 | This determines external refresh factor maximum for calculating the external expire towards the registrar. |
| alwaysRandomIntExpires | O | enumeration | disabled | This controls how the random value is used for internal expires If set to disabled, the internal timeout value is randomized for only initial REGISTER message.. If set to enabled, the internal timeout value is randomized for all REGISTER messages (initial and refresh) |
| alwaysRandomExtExpires | O | enumeration | disabled | This controls how the random value is used for external expires If set to disabled, the external timeout value is randomized for only initial REGISTER message.. If set to enabled, the external timeout value is randomized for all REGISTER messages (initial and refresh) |
| useRUriForRegisterRouting | O | enumeration | disabled | If enabled, will perform request URI based routing of the received REGISTER message. |
| preserveRcbOnRefreshRegErrResponse | O | enumeration | disabled | If enabled, RCB will not be deleted on receiving error response(4xx/5xx/6xx) for Refresh Registration. This RCB will be preserved untill last negotiated/active registration timer expires and SBC allows if any new calls/non-invite requests received from this registered user. If disabled, Existing behaviour(RCB will be deleted after 64 seconds). |
