This screen defines the parameters controlling registration relay behavior.
On the SBC main screen, choose a path:
Select a specific Address Context, Zone, and SIP Trunk Group. The Registration window is displayed. Signaling Registration Parameters Parameter Length/Range Description Require Registration N/A Use this feature to specify the type of endpoint registration validation required. Supported-group – Accept registrations from unregistered users and from users whose user names do not match with the stored URI in Registration Control Block. If an endpoint is registered, then the registration data is used to send calls to that endpoint instead of PSX route. NOTE: Set Require Registration to "Supported-group" for the IP Peer on which surrogate registration functionality is enabled. NOTE: In loopback scenarios for SIP-H.323 calls, you must set Require Registration to "None." Expires The time (in seconds) a SIP endpoint's registration session lasts before requiring re-registration. This value does not apply if the endpoint is NATted. The default value is 3600. Inside Expires Minimum 0-100000 Controls the initial expire value (in seconds) in a REGISTER relayed to a registrar. The default value is 3600. NOTES: Include XOriginal Addr N/A Enable this flag to insert the X-ORIGINAL-ADDR header into the REGISTER message. Bulk Register Format N/A Use this flag to determine how the registration requests are formatted with respect to RFC 6140. Defines the minimum factor for random number calculation for internal refresh timeout. The default value is 0. 0-1000 Defines the maximum factor for random number calculation for internal refresh timeout. The default value is 0. NOTE: If Int Refresh Factor Max is less than Int Refresh Factor Min or if both parameters are set to 0, the random factors are ignored and the timeouts or the deadlines are calculated using a random number between x and x/2. Defines the minimum factor for random number calculation for external refresh timeout. The default value is 0. 0-1000 Defines the maximum factor for random number calculation for external refresh timeout. The default value is 0. NOTE: If Ext Refresh Factor Max is less than Ext Refresh Factor Min, or if both parameters are set to 0, the random factors are ignored and the timeouts or the deadlines are calculated using a random number between x and x/2. N/A If enabled, the internal expire timeout will be randomized for the initial and the refresh REGISTER. If disabled, the internal expire timeout will be randomized for the initial REGISTER. N/A If enabled, the external expire timeout will be randomized for the initial and the refresh REGISTER. If disabled, the external expire timeout will be randomized for the initial REGISTER. N/A If disabled, the Global Loop Detection flag takes precedence. If enabled, Loop Detection is disabled, irrespective of the Global Loop Detection flag setting. N/A Enable this flag to allow the SBC to preserve the RCB on receiving error response (4xx/5xx/6xx, except 401, 407, 408, and 7xx) for the Refresh REGISTER. If disabled, the SBC deletes the RCB.
