18.1.3 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.
18.2 Configuring Proxy and Registration Parameters
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 'Configuration
Parameters Reference' on page 1055. To configure Proxy servers (Proxy Sets), see
'Configuring Proxy Sets' on page 380.
Note: To view the registration status of endpoints with a SIP Registrar/Proxy server,
see 'Viewing Registration Status' on page 949.
 To configure the Proxy and registration parameters:
1. Open the Proxy & Registration page (Setup menu > Signaling & Media tab > SIP
Definitions folder > Proxy & Registration).
2. Configure the parameters as required.
3. Click Apply.
 To register or un-register the device to a Proxy/Registrar:
 Click the Register button to register.
 Click Un-Register button to un-register.
Instead of registering the entire device, you can register specific entities as listed below by
using the Register button located on the page in which these entities are configured:
 FXS/FXO endpoints, BRI endpoints, Trunk Groups - Trunk Group table (see
Configuring Trunk Groups on page
517)
 Accounts - Accounts table (see 'Configuring Registration Accounts' on page 395)
