Signalling and media path topology when both clients are located
in or near the same data center
In the following topology example, there are two data centers with one Avaya Aura
®
Web Gateway
in each data center. Two clients are located in or near the same data center (DC1):
• The first client is located outside the firewall.
• The second client is located inside the enterprise network.
Both clients are registered on the Avaya Aura
®
Web Gateway to receive calls. When one client
makes a call to the other, the call follows the following flow:
1. Both clients log in to the Avaya Aura
®
Web Gateway and activate the call service.
Both clients resolve the FQDN to the address of the load balancer deployed on DC1 and
communicate with the Avaya Aura
®
Web Gateway deployed on DC1.
2. The external client initiates the call.
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 the same Avaya Aura
®
Web
Gateway deployed on DC1, where the internal client is logged in.
5. The Avaya Aura
®
Web Gateway deployed on DC1 uses the Session Border Controller and
Avaya Aura
®
Media Server deployed on DC1 to pass the media through to the internal
client.
