Creating entity links
For each SIP entity communicating with the Avaya Aura
®
Session Manager, an entity link needs
to be configured. That includes one for each B5800 Branch Gateway.
1. On the System Manager console, in the left navigation pane, select Routing >
Entity Links.
2. On the Entity Links page, click New.
3. In the Name field, enter a name to describe this link.
4. In the SIP Entity 1 drop-down box, select the name of the Session Manager system
that is at one end of the link.
SIP Entity 1 must always be a Session Manager instance. For a Session Manager
line from a B5800 Branch Gateway system, this should match the Session Manager
set as the SM Address in the Session Manager line’s configuration.
5. In the Protocol drop-down box, select TCP.
When TCP is selected, the Port field is automatically set as 5060. This is the port
to which the SIP Entity 2 sends SIP requests.
6. In the SIP Entity 2 drop-down box, select the name of the B5800 Branch Gateway
system that is at the other end of the link.
When you selected TCP in the previous step, the Port field was automatically set
as 5060.
7. Select the Trusted check box.
