Registrar Stickiness

You can enable the Registrar Stickiness feature per Account. Registrar Stickiness binds an

Account to one of the IP addresses (configured or DNS-resolved) in the Proxy Set associated with

the Serving IP Group. Once an Account registers successfully to one of the IP addresses (i.e., SIP

registrar server) in the Proxy Set, the device routes all subsequent SIP requests (INVITEs,

SUBSCRIBEs and REGISTER refreshes) of the Account to this registrar. This applies until the

registrar is unreachable or registration refresh fails, for whatever reason.

To configure the Registrar Stickiness feature, use the following parameters in the Accounts table:

Registrar Stickiness: Enables the feature.

Registrar Search Mode: Defines the method for choosing an IP address (registrar) in the Proxy

Set to which the Account initially registers and performs registration refreshes. Once chosen,

the Account is binded to this registrar.

Reg Event Package Subscription: Enables the device to subscribe to the registration event

package service (as defined in RFC 3680) with the registrar to which the Account is registered

and binded. The service allows the device to receive notifications of the Accounts registration

state change with the registrar.

The Proxy & Registration page allows you to configure the Proxy server and registration

parameters. For a description of the parameters appearing on this page, see

Reference. To configure Proxy servers (Proxy Sets), see
