IP Office branch solution architecture

Figure 1. IP Office branch solution architecture
This illustration depicts the distributed, centralized, and mixed architecture of an IP Office branch solution. You can start off with the standalone deployment option and then slowly evolve the solution architecture into a centralized environment as your enterprise grows.

The following table describes how the applications and services in a branch office solution interact with each other.

Component Description
IP Office branch solution This solution includes hardware and software components. Each branch consists of an IP Office system.
Main Avaya Aura® network
  • System Manager provides administrative functions that administrators can use to easily manage all users and IP Office systems in the enterprise. In a distributed, mixed, or centralized environment, IP Office branches connect to the IP Office server.

    System Manager does not manage the following applications: Voicemail Pro, CCR, and UCM.

  • Session Manager connects branches to each other and to other applications and services in the enterprise center. For IP Office users in distributed and mixed deployment environments, Session Manager acts as a SIP proxy to route SIP sessions to and from the SIP connections to IP Office. For centralized users, Session Manager is also the main interface that handles user registration and routing of calls.

  • Communication Manager provides telephony services to centralized users through Session Manager.

  • Avaya WebLM is included within System Manager and provides centralized licensing management.

  • Secure Access Link (SAL) provides remote access and alarm reception capabilities. The SAL Gateway is installed on Linux® Operating System in the customer network and acts as an agent on behalf of several managed elements. All communication uses encapsulated Hypertext Transfer Protocol Secure (HTTPS).

  • Other centralized services such as conferencing and messaging are available to centralized users. Some of these services are also available to IP Office users in distributed and mixed branch environments.
