Configuration manual

Procedure
1. From the System Manager console, select the B5800 Branch Gateway device and
click Edit to edit the system configuration for the device. IP Office Manager will be
launched on your PC. For more information, see Editing a B5800 Branch Gateway
system configuration from System Manager on page 159.
2. In the left navigation pane, click System.
3. Click the LAN1 or LAN2 tab as appropriate depending on which branch site LAN
interface will be used for the data connection to the Avaya Aura
®
network.
4. Confirm that the IP address and IP Mask fields are set correctly for the site.
5. Click the VoIP tab.
6. Select the SIP Trunks Enable option. This is required for Avaya Aura
®
Session
Manager trunk support.
Note:
The SIP Registrar Enable setting and settings in the SIP Registrar tab relate to
SIP extension support and therefore do not affect Avaya Aura
®
Session Manager
lines. The settings in the Network Topology tab relate to external SIP trunks.
Those settings are not used by Avaya Aura
®
Session Manager lines, which use
open internet across the customer WAN.
7. Click OK.
8. Select File > Save Configuration.
The Send Configuration window appears and the Configuration Reboot Mode is set
to Immediate. Do not change the reboot mode.
Setting the branch prefix and local number length for extension
numbering
About this task
Each B5800 Branch Gateway system in the network should have a unique branch number.
That number is added as a prefix to the caller's extension number for calls routed from native
extensions to the Avaya Aura
®
Session Manager. This means that native extensions are
defined on the B5800 Branch Gateway without the branch prefix, so that when the branch
prefix is added, the number is the correct length and format expected by Avaya Aura
®
Session
Manager.
The prefix is also used in the Avaya Aura
®
Session Manager configuration to create unique
dial patterns for routing calls to the appropriate B5800 Branch Gateway.
