b. A client in data center 2 (DC2) gets the address of the DC2 load balancer and
communicates with the Avaya Aura
®
Web Gateway deployed on that data center. The
Avaya Aura
®
Web Gateway registers the client to the corresponding Session Manager
deployed on DC2.
2. The DC1 Avaya Aura
®
Web Gateway initiates the call. To route the media, the Avaya Aura
®
Web Gateway uses the Session Border Controller and Avaya Aura
®
Media Server
deployed on DC1.
3. The Avaya Aura
®
Web Gateway sends the SIP call to Session Manager deployed on DC1.
4. Session Manager deployed on DC1 forwards the call to Session Manager deployed on
DC2.
5. Session Manager deployed on DC2 forwards the SIP invite to the Avaya Aura
®
Web
Gateway from DC2, where the second client is logged in.
6. The Avaya Aura
®
Web Gateway from DC2 uses the Session Border Controller and Avaya
Aura
®
Media Server deployed on DC2 to pass the media through the firewall to the second
client.
