Avaya has created this centralized conferencing solution for small enterprises. The solution offers the full range of Avaya Meetings Server features, particularly multiple simultaneous conferences. The solution is suited for enterprises with a single main branch containing several meeting rooms.

The solution is called Avaya Meetings Server for Over The Top when it ties to the customer existing infrastructure and provides services over the top of this infrastructure without requiring it to be upgraded or replaced.

The following figure illustrates a basic Over The Top deployment.

This complete centralized conferencing solution:

• Targets up to 5,000 registered users.

• Supports up to 500 concurrent sessions.

• Requires port-based licenses

• Recommends the use of two DMZ zones with three firewalls: the web zone for publicly accessed servers; the application zone for application servers.

• Includes Avaya Meetings Management for managing the organization’s network, web-services, and signaling/control components. The virtual application fully integrates with the enterprise active directory and provides intelligent cross-zone bandwidth management regardless of protocols being used for calls. The application deploys as an All-In-One Open Virtualized Appliance (OVA). All its modules (Management, SIP B2BUA, H.323 Gatekeeper, Avaya Meetings Control, Web Gateway, User Portal) are installed on the same virtual machine.

• Deploys Avaya Meetings Media Server that provides rich audio, video, and data conferencing functionalities to the solution. The server includes: HD video transcoding Media Server for processed video, High Scale Audio engine, and Web Collaboration engine. The server supports two working modes per single OVA: video, audio, and web collaboration; high capacity audio and web collaboration. The administrator can switch the working mode from the Avaya Meetings Management interface. Avaya Meetings Media Server cannot work in a mixed mode. For a solution with both working modes, the deployment must include two Avaya Meetings Media Server: one for Full Audio, Video, Web Collaboration, and one for High Capacity Audio and Web Collaboration. For WebRTC, the Avaya Meetings Media Server uses Avaya Aura® Media Server as a WebRTC Gateway.

  To handle WebRTC calls in Over The Top from release 9.1 SP3, Avaya Meetings Media Server instances are configured to run as a WebRTC Gateway and front other Avaya Meetings Media Servers.

• Deploys Avaya Meetings H.323 Edge. The server provides firewall and NAT traversal for Avaya remote H.323 video HD room systems and standard third-party rooms. The server is installed as an OVA.

• Supports Avaya Session Border Controller or an Avaya-approved edge device, as an option. Avaya SBC provides SIP firewall traversal, HTTP Reverse proxy, and STUN/TURN firewall traversal. Avaya SBC is deployed as an OVA, or as an appliance with pre-installed software.

• Adds the Avaya Meetings Streaming and Recording facility as an option. It is deployed as a pre-installed appliance on Avaya Solutions Platform server.
