Telephony View of Cisco Campus in 1999
First Large-Scale Production Cluster Coexisting with PBXes
• Initially with CCM 2.4 and
Cisco SP-12 and VIP-30 IP
Phones (directly from
Selsius acqusition)
• This identified some userrelated issues (AC power
supplies problems, „too
warm” handsets ☺ )
• ... as well as some
unexpected network issues
(QoS in the LAN, IP
addressing requires proper
design using RFC 1918)

Cisco Field Offices in EMEA
Before the migration to Cisco IPT...
• Typically 50 - 200 employees
Some 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

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-user
intenal calls, but primarily for conference calls and accessing
various 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

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
