Avaya Communication Manager Solutions / Cisco Call. Manager Reliability, Availability, Survivability – Large Scale Cisco redundancy achieved by distribution across servers – 30, 000 sets backed up • Eight clustered Call. Managers required (1: 1 redundancy) • Careful partitioning (CCM Groups) must be administered across servers – Connection-preserving (call preserved with no features at time of failure) • Connection preservation is not supported across the following devices: Annunciator, H 323 devices, CTI applications, TAPI applications, JTAPI applications, some IOS gateways. – Failover in minimum of 30 seconds Avaya S 8720 Server Pair – One server for call processing, one for failover – Virtually instantaneous failover – Up to 36, 000 sets backed up – Call-preserving (all functionality maintained on calls in progress at time of failure) © 2005 Avaya Inc.

Avaya Communication Manager Solutions / Cisco Call. Manager Reliability, Availability, Survivability – Small Scale Cisco SRST (Survivable Remote Site Telephony): Router-based – Does not support various Cisco Call. Manager applications or services – Example: Cisco IP Contact Center – Supports a small number of phones on routers – When more than 1 Call. Manager is in a set’s failover list, 30 seconds per Call. Manager will be added to the failover time – 7902, 7905, and 7912 sets take approximately 2. 5 minutes to failover – In SRST mode, only basic features survive Avaya LSP (Local Spare Processor) – Each Media Gateway LSP supports 450 phones – In LSP mode, all features survive © 2005 Avaya Inc. All rights reserved. 27

Avaya Communication Manager Solutions / Cisco Call. Manager Reliability, Availability, Survivability – SUMMARY An Enterprise running Avaya Communication Manager Solutions with main and branch locations – With LSP if the main location fails, all the endpoints at the main location can be controlled and maintained by the processor at the branch location – Link Bounce Resiliency results in “connection preservation” Stateful redundancy vs. connection preservation – Avaya offers stateful server duplication with patented memory shadowing – voice path plus features are preserved during failover – Cisco preserves only the voice path during failover © 2005 Avaya Inc.

Avaya Communication Manager Solutions / Cisco Call. Manager and Linux CCM 5. 0 announced March 2006 CCM 5. 0 is Linux-based Why move Call. Manager to Linux? – Security Concerns – Stack of Pain Security Concerns + Administration Costs _________ Higher TCO! © 2005 Avaya Inc. All rights reserved. 29

Call. Manager 5. 0 (the good) Major features: – Appliance (No more Windows patches!) – SIP and (basic) presence capabilities – Japanese, Chinese, and Korean localization (for phones; needs new models) Copied several Avaya features – True appliance – Dual partitions • Ability to copy in new software while the system runs • Ability to go back to a previous version even in smaller single drive servers – No root access (even more limited than Avaya; no Linux access) – Single image (OS and Application) upgrades – Internal firewall © 2005 Avaya Inc. All rights reserved. 30

Call. Manager 5. 0 (the not so good) Does not have feature parity w/ Call. Manager 4. 2 (Windows) until Call. Manager 5. 1 or 6. 0 release (5. 1 rumored for early 2007; 6. 0 late 2007). Creates several logistical problems – If customers choose Call. Manager 4. 2 there is no clear upgrade path to 5. 0 (for some time) – IPCC Express v 4. 5 required (no technical upgrade path from previous versions, no HA, or expansion) – Some apps are not supported. Examples: • Personal Assistant: Workaround is to use Unity Connection (Unity Enterprise does not offer find-me/follow-me). UC has call transfer based on caller, To. D, Calendar (Exchange only). • Conference Connection: Must upgrade to Meeting. Place – Most 3 rd party management products need new versions to work with the new API’s and ways to manage them (no 3 rd party agents supported) Many of the other adjunct servers are still Windows based: Emergency Responder, IPCC, Unity. © 2005 Avaya Inc. All rights reserved. 31

What Doesn’t Change Cluster approach with multiple servers to maintain Single point of failure with one database (Publisher) Lack of feature richness results in adjunct server applications and interfaces to manage – E-911 (Emergency Responder) – Extension to Cellular (Mobility Manager with Mobile Connect app) – Enhanced Presence – (Presence Server for CCM 5. 0 only) – Small Contact Center (Customer Response Suite) – Large Contact Center (ICM, IP IVR, CVP) Result: Complexity of management, call flows and interactions © 2005 Avaya Inc.

Which Call. Manager Version? – A Customer Dilemma If customer chooses 4. x – Comes with Windows headaches and higher TCO cost • Per server, 167 minutes per upgrade and $67, 559 3 year TCO – No support for SIP endpoints or Presence If customer chooses 5. 0(4) – Enterprise is running on an unproven platform and considered experimental by customers and partners – Less features than 4. x – Native SIP support but • still needs external server for presence • Advanced SIP features for Cisco phones only – Interoperability issues with other applications • No support for IPMA and Conference Connection • Requires specific version of IPCC Express (no hot standby IPCCX option) © 2005 Avaya Inc.

Avaya Communication Manager Solutions / Cisco Call. Manager Telephony Feature Differentiators Avaya’s support of sophisticated bridging and extensive call coverage paths versus simple call forwarding from Cisco provides significant power in customizing call handling operations Only Avaya offers Whisper Page to allow a secretary to convey a message to the principle without the person he/she is talking hearing the Whisper Page Only Avaya has sophisticated Night Service, Send All Calls, Manual Signaling, Service Observing, and many more Only Avaya allows Group Paging to utilize the speakers of the telephones as a paging system Only Avaya has an integral “Hoteling” feature – Unlike Cisco’s Extension Mobility feature, no administration and external authentication application is required © 2005 Avaya Inc. All rights reserved. 39

Avaya Communication Manager Solutions / Cisco Call. Manager Security / Privacy / Safety Differentiators Avaya has E-911 built into Communication Manager and works equally well with any IP infrastructure – Cisco requires a separate Emergency Responder server which has to be duplicated for redundancy – For complete redundancy every site with Call. Manager servers requires duplicated E-911 servers to safeguard against losing E 911 support in the event of a WAN outage – Small locations relying on SRST survivability software in routers lose E-911 capability in the event of a WAN outage – The server administered separately from Call. Manager – Cisco’s solution is optimized for performance on their own infrastructure © 2005 Avaya Inc. All rights reserved. 40

Avaya Communication Manager Solutions / Cisco Call. Manager When Call. Manager 4. 0 was announced, Cisco touted the Malicious Call Trace feature – – No support over QSIG No support over MGCP gateways No support over Analog gateways No support inter-cluster Crisis Alert feature is Emergency Responder based, external to Call.

Security Analysis Detail © 2005 Avaya Inc. All rights reserved. 46

Key Points on BCR Security Analysis At the time Avaya Communications Manager, per BCR “does not, strictly speaking, encrypt H. 323 call control”, resulting in loss of 1 point – Encrypted H. 323 call control was added in CM 3. 1 Cisco lost 1 point for lack of universal media encryption, still not available Avaya lost ½ point for “other” such as documentation, services offered, affiliation with 3 rd party vendors, documented enhancements, etc Six Cisco engineers spent several hours deploying security on site in preparation for the BCR testing – Reason: Overall security for Call. Manager is heavily dependent on L 2/L 3 network infrastructure components and firewalls, some of which are optional, added cost components Traditional security risks, i. e. toll fraud protection factored lightly by Mier © 2005 Avaya Inc. All rights reserved. 47

Call. Manager Security Issues Cisco IPT security approach is heavily dependent on security defenses integral to its Layer 2 and 3 devices and firewall platforms – Conclusion: properly deployed these defenses can be leveraged with any IPT platform, including Avaya’s Relies on integral ‘host-based’ intrusion-prevention-system (HIPS) software modules to protect server from high-level assaults – No ability to physically isolate call processing servers from “public IP network” • Reason: IP Phones register directly to Call. Manager servers Media Encryption – – Not supported on all IP phone models Only supported on certain gateways No encryption for conference calls and between clusters Voice quality drops significantly with encryption enabled (MOS 3. 2 vs Avaya 4. 3) – 15 to 20% reduction in system performance when activated © 2005 Avaya Inc.

In Summary, BCR 2006 Report Says it All © 2005 Avaya Inc. All rights

Cisco Claim Rebuffed Claim: A Cisco single-vendor approach has lower TCO … Infotech says 57% of enterprises have multi-vendor environments. Gartner says that Cisco has sought to promote lock-in to their offers “where not appropriate. ” Computer. Weekly survey of 800 senior IT executives: • • 58% had negative experiences with single supplier lock-in 35% had to purchase products that did not meet their needs 18% had to purchase unnecessary hardware 67% said they had experienced pressure from vendors to buy only from them Avaya solutions work in multi-vendor environments, require no forklift, enjoy many years of vendor support, and use lower-cost (and lower-downtime) Linux operating systems. © 2005 Avaya Inc.
