Instructions for modifying/creating a SIP Server Table entry are below. To add a SIP Server table, see Managing SIP Server Tables.
- Multiple entries of the same server type (IP/FQDN or DNS-SRV) can be added to a SIP Server Table, but only one type of server is allowed per table. For example, if you add a SIP Server as DNS-SRV, the other entries in the same table must be specified as DNS-SRV; to add a Server Lookup as IP/FQDN, you must create another table.
- Only one domain name and protocol are permitted in a SIP Server Table. If the domain name and protocol are used in one entry, they cannot be used in an additional entry in that same table.
- Only one domain name per SIP Server table can be selected as the Server Host.
Creating an Entry in a SIP Server Table
- In the left navigation pane, go to SIP > SIP Server Tables. Click on the desired SIP Server Table.
From the Create SIP Server drop down list, select IP/FQDN or DNS-SRV. The associated configuration screen is displayed.
NoteFederated IP addresses and FQDNs specified in a SIP Server Table are whitelisted.
- Configure the options. See Field Definitions.

Server Host - Field Definitions
Server Host - For IP/FQDN only
Server Lookup
This field is populated automatically when you add a SIP Server table entry and select IP/FQDN Lookup from the Create SIP Server drop down box. IP/FQDN enables the SBC to select the server containing the specified IP address or Fully Qualified Domain Name (FQDN) to which this Signaling Group sends SIP messages.
Priority
Specifies the priority of this server. The priority is used to order the server when more than one is configured. If Load Balancing is configured as Round Robin or First in the SIP Signaling group, the Priority field is not used to determine the priority of the server. See Creating and Modifying SIP Signaling Groups.
Host
Specifies an IP address or Fully Qualified Domain Name (FQDN) to which this Signaling Group sends SIP messages.
If an FQDN is configured all the associated servers are included and used according to the server selection configuration element.

Remote Authorization and Contacts - Field Definitions
For IP/FQDN entries in SIP Failover mode, when there are multiple SIP Server entries, the configuration in Remote Authorization and Contacts must match the configuration for other SIP Servers.
The Remote Authorization Table and Contact Registration Table configuration is shared between the Primary and Secondary SIP Server entries; only the one provisioned in the Primary SIP Server is used.
Remote Authorization Table
Contact Registrant Table
Specifies a Contact Registration Table for this SIP Server from the list of registration tables defined in the Contact Registrant Tables.
The Contact Registration is used by a Signaling Group to register one or more contacts to a registrar. The contact information contains the SIP address of record and the methods which can be used to establish sessions to this Signaling group. Valid entry: Select from the list of Contact Registrant Tables or select None. If you select a Contact Registrant from the list, the following fields are displayed: Clear Remote Registration on Startup, Contact URI Randomizer, and Stagger Registration.
Clear Remote Registration on Startup
Contact URI Randomizer
Stagger Registration
Enables Registration (and Unregistration) Requests to be staggered by one second if more than one Contact Registrant entry is in the Contact table. This field is visible only when Contact Registration Table is set to a configuration other than None. Valid entry: True (registration requests are staggered) or False (registration requests are not staggered). Default entry: False. When Stagger Registration is set to True, the maximum number of contact registrant entries configured should not exceed 500. If more than 500 are entered in configuration, they will be dropped and an ERROR trace is generated.
Stagger Registration does not take effect if the SIP Failover feature is enabled.
