• Initially with CCM 2.4 andCisco SP-12 and VIP-30 IP Phones (directly fromSelsius acqusition)

• This identified some user-related issues (AC powersupplies problems, „toowarm” handsets ☺ )

• ... as well as someunexpected network issues(QoS in the LAN, IP addressing requires properdesign using RFC 1918)

• Later with CCM 3.0 - bettervoice quality with Cisco IP 7960 phone and properQoS allowed this phase to finish successfully

• Lessons learned: QoS inthe LAN and in-line poweris a must !

Cisco Field Offices in EMEABefore the migration to Cisco IPT...

• Typically 50 - 200 employeesSome Core offices with 1500+ users

Flash-Cut Approach becomes viable option !

• Voice architecture in Cisco EMEA before migration: Avaya Definity PBXs (also few Nortel in other theatres)with 28 Centralized Octel Voice Mail Systems

• Portable, easy to install

• WAN/LAN connectivity

• File/Print/DHCP Server

• UPS

• Complete IP Telephony environment

• Minimum onsite involvement


Why CCP = Centralized Call Processing ?

• After migration to IP NGN – MPLS VPN from C&W (SLA on Bandwith, Latency, Jitter) we could finally do that !

• Extension Mobility within Cisco EMEA region (mobile workers in Europe/MiddleEast/SouthAfrica)

• Cost savings through internal VoIP (not only for user-to-userintenal calls, but primarily for conference calls and accessingvarious internal helpdesks, located primarily in Amsterdam, London and Brussels)

• Cost savings through international hop-off

• XML Applications for all sites (single core-instance)

• Lower TCO, Improve Manageability (global support)

• Our rollout not how customers would do it so far …

CCP – Example of Cost Reduction:Capital Expenditure & OS Maintenance

• Capital Expenditure (Example – Cisco EMEA)60 Offices: 11 Servers only vs. ~100 servers in pre-CCP !!!

• Saving in headcount:Assumption: on average 1hr/month/server for pro-active OS patching/upgrade is required

Pre-CCP: 50 sites x 2 servers x 1 x 12 months = 1440 man hours = ~ 0.66 year SysAdmin HC

Post-CCP: 11 servers x 1 x 12 months = 132 man hours = 0.06 year SysAdmin HC

CCP is now the Global Architecture for Cisco’s own IP Telephony System


Executive Summary

• Reduced 262 PBXs to 13 IP Centralized Call Manager Clusters

• Removed lease costs of PBXs: $1.5 Million / year in San Jose

• Removed contracted maintenance costs of PBXs: $2.2 Million / year in San Jose, $4M/year total in all the Americas

• Worldwide Central Voice Management in place• Converted 18,000 Voice Mail users across US in

one weekend• Added worldwide voice mobility

In the office, at home, and on the road• MeetingPlace and Cisco Video Telephony

Advantage rolling out now


IP Communications

• Centralized call processing with distributed CallManager Cluster – 2 x MCS-7825, one CM at Central Office and one in DR Site

• All locations covered with IPT, more than 600 IP Phones mainly 7912 , 7940 & 7960 for managers and 7936 in conference rooms

• CM at Central Office roles: primary server for call processing, subscriber CM server, Music on Hold streaming server and Conference Bridge server

• CM at DR Site roles: publisher CM, secondary server for call processing and TFTP server

• Voice Gateways have 2 x ISDN PRI in central sites and regional offices and ISDN BRI in branches for connection to PSTN

• No analog phones and no traditional PBX`s !


IP Communications• SRST in remote locations• Intercluster CallManager Trunks with CallManager Clusters in

Bulgaria and Greece• Complex, but functional dial plan enables the users to identify

the branch of the calling number and the position of the person in the branch

• For incoming calls, some dialed ISDN numbers are directly answered by Branch and Platform Managers. For Accounts and Tellers there are Hunt group numbers configured on the CM that directly distribute the call to the first active employee

• QoS mechanisms - Low Latency Queuing, RTP header compression and Link Fragmentation with Interleaving

• Call Admission Control to control number of calls that can be established over WAN link

• CiscoWorks QoS Policy Manager


IP Communications – next steps

• New 20 branches by the end of the year

• IPCC Express with database dips and voice recording

• ERS Euroline Retail Services network connecting to EFG network – Avaya out , Cisco in with new 180 IP Phones

• Acquisition of Nacionalna Štedionica banka with 68 branch officess – plan to integrate this network to EFG Eurobank network with IPC as well !


Network and IPC

• Central Office, Brewery and Mega Market in Novi Sad: 2 x redundant Catalyst 4507R switches in core, 3550-24 PWR switches in access; 2 x MCS-7825 CallManager servers, 2 x 3725 VG each with ISDN PRI to PSTN

• More than 500 IP Phones: 7970, 7960, 7940, 7912 and 7902

• 3725 Router for aggregation

• WLAN network with AP1200

• WLAN clients : IP phones 7920, PDAs, Laptops

• Remote Sites with

1760 SRST routers
