4 4 © 2005 Avaya Inc. All rights reserved. Value Proposition of IP Telephony Consolidation communications solution and supporting applications –Reduce upgrade costs - rather than having to upgrade many remote systems, only one instance of Communication Manager needs to be upgraded –One place to administer features - no need to have staff at remote locations to add users, etc. –Reduce the application infrastructure, again through consolidation –Efficiencies gained and costs reduced through centralized trunking. Centralize your applications and dilute costs over a larger community of users –CTI, UM, speech access, call recording, workforce management, and reporting can be deployed at one location –Consistent set of announcements with the same voice and message, for the entire enterprise.

5 5 © 2005 Avaya Inc. All rights reserved. Local Survivable Processor (LSP) CM 1.1 –Allows continued service should there be a failure from the server to the remote site –Provides survivability for G250, G350 or G700 and IP endpoints Enterprise Survivable Servers (ESS) – CM 3.0 –Provides protection from catastrophic server failures and from network fragmentation –When ESS is in control, provides full feature functionality as the main server –Provides survivability for Port Networks – G650, G600, SCC, MCC, CMC Connection Preserving Failover/Fallback for H.248 MGs (LSP) CM 3.0 –Preserve existing calls when gateway switch to CM server Auto Fallback to Primary for H.248 Gateways (LSP) CM 3.0 –Provides an automatic mechanism for returning H.248 gateways (G250, G350, G700) that are being serviced by an LSP back to the primary server Inter Gateway Alternate Routing CM 3.0 –Alternative path using PSTN when IP-WAN is incapable of carrying bearer connection Standard Local Survivability (SLS) CM 3.0 –Provides survivability for the G250 when there is a primary link failure Value of High Availability and Survivability

9 9 © 2005 Avaya Inc. All rights reserved. Business Continuity Business Continuity Enterprise Survivable Servers (ESS) allow backup servers to be placed at various places in a your network so that your communications can continue to operate in the event that the main server fails, or when connectivity to the main server lost Flexibility Flexibility Mixed Port Network Connectivity allows Multi-Connect PNC and IP PNC configurations to co-exist in the same network allowing you to leverage IP telephony selectively where it can benefit you the most Scalability Scalability The IP Media Resource 320 provides up to ten times the IP processing capacity as the current IP Media Processor. Whats New with Communication Manager 3.0?

10 10 © 2005 Avaya Inc. All rights reserved. Mixed Port Network Connectivity CM 3.0 Allow Multi-Connect PNC and an IP PNC to co- exist in a single communication system –Add remote sites or merge other systems into the main using IP PNC with choice of availability options –Move from a Direct Connect or CSS architecture to an IP PNC architecture over a period of time –Increase the number of port networks supported in a CSS configuration by adding additional IP connected port networks to achieve a maximum of 64 port networks

11 11 © 2005 Avaya Inc. All rights reserved. Enterprise Survivable Server CM 3.0 Enterprise Survivable Servers allow backup servers (S8500 or S87XX) to be placed at various places in a your network so that your communications can continue in the event that the main server(s) fails, or when connectivity to the main server(s) is lost Enterprise Survivable Servers can be deployed where needed throughout your network to provide increased communications continuity –The IPSI card in the port networks automatically obtains service from an ESS server(s) if the control signal to the main server is lost Enterprise Survivable Servers can be connected to ATM, IP and Center Stage Switch (CSS) connected port networks
