Administering a Session Manager line for each branch
This section provides the procedures required to configure a Session Manager line between
each branch site and the headquarters site.
This section also describes how the B5800 Branch Gateway uses a configured Session
Manager line to handle incoming and outgoing calls to and from the branch and explains how
a second Session Manager line can be configured for Session Manager line redundancy.

Enabling SIP trunk support
About this task
Before adding any SIP trunks, includingAvaya Aura
®
Session Manager lines, the B5800 Branch
Gateway system must be configured for SIP trunk operation. The system has 2 LAN interfaces,
LAN1 and LAN2 (the physical ports are labeled LAN and WAN respectively). Either can be
used for the Avaya Aura
®
Session Manager line operation.
