Design Clinic Cisco UC Architecture for Corporate Branch

Point of this Session: Two solutions – Same destination © 2007 Cisco Systems, Inc.

Agenda Customer Scenario “Standalone” Approach “Centralized” Approach Summary © 2007 Cisco Systems, Inc. All

Primary Focus § Voice (Call Control) § Voicemail © 2007 Cisco Systems, Inc. All

Customer Scenario § Branch Offices “X” number of sites – might acquire 10 more 12 – 75 people each Couple just 2 users Fax or two, some analog trunks, larger sites have PRI § Corporate IT/Telecom (help) manage branch systems § Standardize (features, components) § “ 4 -digit” dialing § Lower Costs / Reduce Long-Distance § Migration – Slow rollout Interoperate w/ HQ PBX © 2007 Cisco Systems, Inc. All rights reserved. Cisco Public 5

Devil’s in the details § High level requirements can mean more than one thing § Nip “ 4 -digit” dialing now – look to Universal Dial Plan § How standard? Literally one-size fits all or just similar technology? § Willing to adjust WAN/other to support Voice goals? § Interop – define please © 2007 Cisco Systems, Inc. All rights reserved. Cisco Public 6

More devilish details § Call Control Single PBX? Or networked independent? § Voicemail All on central? Or each site have own Voicemail? § If each have own – still be able to transfer/forward to central? Between branches? § Network with legacy VM at HQ? We’ll explore above © 2007 Cisco Systems, Inc.

Approach One © 2007 Cisco Systems, Inc. All rights reserved. Cisco Public 8

Approach One § Per site Voice and Voicemail § Cisco Unified Communications Manager Express

How CUCME/CUE fits criteria § “Buy as you grow” § Leverage H. 323 for inter-site calling § Can use variety of ISR sizes – still ‘standardized’ § CUE for per-site VM § Remote management by central support team § Use Voice Gateway to connect to HQ PBX © 2007 Cisco Systems, Inc. All rights reserved. Cisco Public 10

CUCME/CUE - Step One • 1861/2800/3800 size to # phones BRANCH “A” 1861 (8) to 3845 (250) • Local phones • PSTN trunks Analog VIC PRI VWIC • CUE licensed for # mailbox AIM-CUE PSTN FAX NME-CUE © 2007 Cisco Systems, Inc. All rights reserved. Cisco Public 11

CUCME/CUE – Add branch BRANCH “B” BRANCH “A” CUCME/CUE Voice/Data Network PSTN FAX • Configure dial-peers so can call each other • Separate Voicemail © 2007 Cisco Systems, Inc. All rights reserved. Cisco Public 12

CUCME/CUE – Add HQ BRANCH “B” BRANCH “A” CUCME/CUE Voice/Data Network PSTN FAX WAN router • More dial-peers • Still separate VM © 2007 Cisco Systems, Inc. All rights reserved. V Voice Gateway Cisco Public Voice HEADQUARTERS 13

CUCME/CUE “Final” Solution BRANCH “B” BRANCH “A” CUCME/CUE Voice/Data Network PSTN FAX • Build Slow • Dial anyone • Share VM FAX WAN router V UMG • Manage centrally © 2007 Cisco Systems, Inc. All rights reserved. Voice GK Voice Gateway Cisco Public HEADQUARTERS 18

OPTION - CUCME with centralized voicemail BRANCH “B” BRANCH “A” CUCME Voice/Data Network PSTN FAX WAN router Unity or UConn Voice CUCME MWI Relay © 2007 Cisco Systems, Inc. All rights reserved. Cisco Public HEADQUARTERS 19

Approach Two © 2007 Cisco Systems, Inc. All rights reserved. Cisco Public 20

Approach Two § Cisco’s Centralized Call-processing model § Cisco Unified Communications Manager § Cisco

How CUCM / Unity (or UConn) fit Criteria § Single PBX § “single” point of mangement § Any call any (unless configured not to) § Simpler dialplan management (dialplan itself still pain) § Single VM for everyone § Easy to integrate voice to 3 rd-party PBX, or number of them § More 3 rd-party voicemail integrations. © 2007 Cisco Systems, Inc.

CUCM/Unity - Step One • CUCM • Unity BRANCH “A” • 1861/2800/3800 size to # phones 1861 (8) to 3845 (250) • Local phones Voice/Data Network • PSTN trunks Analog VIC PSTN PRI VWIC © 2007 Cisco Systems, Inc. All rights reserved. Cisco Public FAX 23

CUCM/Unity – Add branch Move/Add/Change to add a site BRANCH “B” BRANCH “C” BRANCH “A” V Voice/Data Network PSTN FAX • Can drop in remote by adding phones • Add gateway as/when needed © 2007 Cisco Systems, Inc. All rights reserved. Cisco Public 24

CUCM/Unity – Integrate HQ BRANCH “B” BRANCH “A” Voice/Data Network PSTN FAX Voice Gateway

CUCM/Unity – Build Out HQ Add phones at HQ BRANCH “B” BRANCH “A” Voice/Data

CUCM/Unity – “Final” Solution BRANCH “B” BRANCH “A” Voice/Data Network PSTN FAX Voice Gateway

What about use existing VM only? § Not really possible with CUCME No SMDI – low chance QSIG (no release transfer) § For CUCM have following options 1) Dual connect 3 rd-party VM 1) Box not likely to be set up for dual integration 2) Use QSIG link from CUCM to PBX © 2007 Cisco Systems, Inc.

Criteria that immediately drive Centralized § True UM Requires Unity w/ customer’s Exchange or Notes Does not require centralized CUCM § Company-wide Presence Requires centralized CUCM w/ CUP § “agents any location” Contact Center Requires centralized CUCM and UCC Express or Enterprise, possibly CVP © 2007 Cisco Systems, Inc.
