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

Those settings are not used by Avaya Aura
®
Session Manager lines, which use
open internet across the customer WAN.

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 to the 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.
By default B5800 Branch Gateway systems use 3-digit extension numbering starting from 200.
The existing allocated numbers can be changed in bulk using the Tools > Extension
Renumber option. This will add or remove a set value from all existing extension numbers in
the configuration.
Procedure
1. Start Manager and connect to the B5800 Branch Gateway system.
2. In the left navigation pane, click System.
