Enabling branch SIP extension support
About this task
Before adding any SIP extensions, the B5800 Branch Gateway system must be enabled for
SIP extension support. Use this procedure to configure the B5800 Branch Gateway to support
the addition of SIP extensions.
Important:
The configuration changes in the following procedure will require the B5800 Branch
Gateway system to be rebooted.
Procedure
1. Start Manager and connect to the B5800 Branch Gateway system.
2. In the left navigation pane, click System.
3. Click the LAN1 or LAN2 tab, depending on which branch site LAN interface will be
used for the SIP extensions.
4. Make a note of the IP Address and IP Mask details as these will be required during
the SIP extension configuration.
5. Click the VoIP tab.
6. Check the SIP Registrar Enable check box. This is necessary for support of SIP
extensions directly by the branch or when providing survivability support for Avaya
Aura
®
SIP extensions.
7. Click OK.
8. Click the SIP Registrar tab.
9. Click the Auto-create Extn/User check box so that it is not checked (the default
setting is enabled).
This setting must be disabled. SIP extensions should only be allowed to register
with the Avaya Branch Gateway B5800 system if they match existing extension and
user entries in the configuration. If a centralized extension (also referred to as a
survivable extension) is allowed to auto create matching entries, the extension's
Extension Mode setting defaults to Local (also referred to as a native extension)
which is incorrect for a centralized extension.
10. Configure the remaining fields on this tab as appropriate. See
SIP Registrar tab field
descriptions on page 175 for more information.
