Avaya vs Cisco Avaya vs Cisco

Why Avaya ? Avaya CM over 700+ Features Avaya CM runs on approximately 10 Why Avaya ? Avaya CM over 700+ Features Avaya CM runs on approximately 10 M lines of code Software Unix to Linux Cisco CUCM over 200+ Feature CUCM runs on approximately 50 M lines of code Software Microsoft to Linux 38

Why Avaya ? Ease of Operation All Avaya servers run exactly the same software Why Avaya ? Ease of Operation All Avaya servers run exactly the same software including remote ESS and LSP, upgrades, patches, adds, moves, changes, vectors, dial plan transparency are all automatically pushed down to survivable servers. Complex Operation Separate software and administration on Cisco’s CUCM and remote SRST Restrictions, announcement script logic, and transparency features have to be configured individually per site. This doubles the Administration task taking up valuable time increasing TCO. 39

Cisco Higher TCO Example Station Administration Cisco CUCM duplicating stations is not easy. Multiple Cisco Higher TCO Example Station Administration Cisco CUCM duplicating stations is not easy. Multiple steps and menus are required. The primary reason for this is the dependency of needing MAC addresses to be entered individually. With Avaya, up to 16 stations can be duplicated at once. At most, only the ‘Duplicate Station’ and ‘Change Station’ commands are required to fully configure an Avaya station. This adds more TCO expense for the high priced Cisco Certified Administrator. 40

Avaya TCO - ESS / LSP - Half the Admin Time #1 – Main. Avaya TCO - ESS / LSP - Half the Admin Time #1 – Main. Server updates remote S 8300 LSP #2 – Remote Adds, Moves and Changes during survivable mode. Full Feature, Functionality Main Remote S 8300 LSP recommended over 250+ Endpoints Single Administration for remote users, patches, upgrades, at one location Upgrades, patches, etc. are single touch 1 x Administration Low TCO 41

Cisco TCO - SRST Twice the Admin Time Main Remotes Publisher SRST Locations #1 Cisco TCO - SRST Twice the Admin Time Main Remotes Publisher SRST Locations #1 Remote SRST Adds, Moves and Changes first go to Publisher Server Besides the Main Location, Every remote SRST will requires constant touches for updates and programming #2 Same SRST Adds, Moves and Changes are then made to the SRST Gateway Upgrades, patches, etc. can add to more touches at STST locations 2 x the Administration. High TCO 42

Avaya Memory Shadowing Adds, Moves and Changers Can be made when S 8800 A Avaya Memory Shadowing Adds, Moves and Changers Can be made when S 8800 A or S 8800 B Fails Adds, Moves and Changes cannot be made when the Publisher fails. Single point of failure DL 360 G 7 - A Publisher DL 360 G 7 - B Subscriber If the active DL 360 Server fails there will be “NO” disruption in feature/function service. For example, Calls can be put on hold, transfer and conference. The two DL 360’s are memory shadowed If the active Publisher Server Fails Active call lose all feature/function Service. For example, calls cannot be put on hold, transfer or conference. The two Servers are not Memory shadowed 43
