Client Enablement Services (CES) provides access to many Avaya Unified Communications (UC) capabilities, including telephony, mobility, messaging, conferencing, and Presence Services through a single application. Avaya one-X® Mobile communicates with the CES server by using the CES protocol. To provide CES services to Avaya one-X® Mobile clients outside the enterprise network, Avaya SBC provides a secure proxy that must be deployed in the enterprise DMZ. Avaya SBC checks all traffic from Avaya one-X® Mobile clients outside the enterprise network to the CES server.
When a new connection is established from an Avaya one-X® Mobile outside the enterprise network:
  • Avaya SBC checks whether the first message from the Avaya one-X® Mobile device is a login request and forwards the message to the CES server. Avaya SBC drops all messages received from the Avaya one-X® Mobile device before the login request.
  • The CES server authenticates Avaya one-X® Mobile or sends an error message to Avaya SBC. After authentication failure, Avaya SBC rejects all subsequent messages from the Avaya one-X® Mobile.
  • After authentication, Avaya SBC forwards all messages from Avaya one-X® Mobile to the CES server.
Avaya SBC maintains statistics for all login attempts. Avaya SBC supports at least 10,000 Avaya one-X® Mobile clients on Dell R630 and HP DL360 G9.
