Parameter | Description |
---|
Require Registration
| Use this flag to specify the type of endpoint registration validation required. Note |
---|
Set Require Registration flag to ‘supported-group’ for the IP Peer on which surrogate registration functionality is being enabled. |
| 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 NAT'd. The value ranges from 15 to 65535 and the default value is 3600. | Inside Expires Minimum
| Controls the initial expire value (in seconds) in a REGISTER relayed to a registrar. The value ranges from 0 to 65535 and the default value is 3600. Note |
---|
- Since the SBC expects an expires value greater than 540 seconds (9 minutes) from the registrar, do not set “
insideExpiresMinimum ” value less than 540 seconds. Ideally, set this value much higher (3600 seconds is recommended) to avoid overloading registrar with register refreshes. - When configuring surrogate registration, be sure to set the expires value of ingress trunk group toward IAD to the maximum default value of “3600”.

| Include XOriginal Addr
| Enable this flag to insert the X Original Addr header into REGISTER message. disabled Disabled (default) enabled Enabled
| Bulk Register Format
| Use this flag to determine how the registration requests are formatted with respect to RFC 6140. disabled Disabled (default) – REGISTER message is not formatted as per RFC 6140. enabled Enabled – REGISTER message is formatted as per RFC 6140. followIngress Follow Ingress – No changes are made to the Egress Register with respect to RFC 6140.
| Int Refresh Factor Min | Defines the minimum factor for random number calculation for internal refresh timeout. The range values from 0 to 1000 and the default value is 0. | Int Refresh Factor Max | Defines the maximum factor for random number calculation for internal refresh timeout. The range values from 0 to 1000 and the default value is 0. Note |
---|
If "Int Refresh Factor Max"
is less than "Int Refresh Factor Min " or both "Int Refresh Factor Max" and "Int Refresh Factor Min" 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. |
| Ext Refresh Factor Min | Defines the minimum factor for random number calculation for external refresh timeout. The range values from 0 to 1000 and the default value is 0. | Ext Refresh Factor Max | Defines the maximum factor for random number calculation for external refresh timeout. The range values from 0 to 1000 and the default value is 0. Note |
---|
If "Ext Refresh Factor Max"
is less than "Ext Refresh Factor Min " or both "Ext Refresh Factor Max" and "Ext Refresh Factor Min" 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. |
| Always Random Int Expires | 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. The options are: disabled Disabled (default)enabled Enabled
| Always Random Ext Expires | 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. The options are: Disabled (default)Enabled
| Use RUri For Register Routing | If disabled, Global Loop Detection flag takes precedence. If enabled, Loop Detection is disabled, irrespective of Global Loop Detection flag. The options are: Disabled (default)enabled Enabled
