1 Evolution & Revolution Avaya s Reference Architecture For Unified Communications Gianluca Attura Amministratore Delegato Avaya Italia S.p.A.

2 Avaya Customer Experiences Challenge From Strategic Customers Heterogeneous multi-vendor mix of TDM and IP Too complex and costly to rip and replace everything How to get significant cost savings now? How to securely add targeted UC applications now? Solution Embrace and Extend Enterprise-wide architecture that saves money while creating business agility Help in strategic communications design and implementation 2

3 Communication Evolution New protocol allows new architecture Pre 2000 IN/SS7 Overlay Today CTI Overlay Tomorrow Peering and Loose Coupling SOA Application Application App App Connection Connection SIP Presence Network IP H.323 Connection ISDN and TDM Network SIP Flatten Consolidate Extend Applications Everywhere (FCE 2.0) Network 3

4 IMS Architecture for Service Providers 4

5 What s IMS IMS = IP Multimedia Subsystem The IP Multimedia Subsystem (IMS) is an architectural framework for delivering Internet Protocol (IP) multimedia services To ease the integration with the Internet, IMS uses IETF (i.e., Internet Standard) protocols wherever possible, e.g., Session Initiation Protocol (SIP) According to the 3GPP, IMS is not intended to standardize applications but rather to aid the access of multimedia and voice applications from wireless and wireline terminals, i.e. create a form of fixed mobile convergence (FMC). 5

6 A structured approach to deploying a SIP architecture Take principles and appropriate SIP standards from 3GPP IMS Uniquely simplify and make practical for enterprise use Three tier architecture, decouples users and access points from applications Provide natural evolution for Avaya Communication Manager customers Existing telephony capabilities become a SIP feature server New feature servers easily added and combined User profiles centrally map users to application IMS defined by 3GPP Avaya Reference Architecture 6
