7 Key Challenges

8 Key Challenges Compute, Storage & Footprint Costs Operational Costs Access Costs Under utilized dedicated VMs are expensive for small and even for mid-market customers Starting cost of HCS DC is also high Initial customer on-boarding cost is significant Customer site deployment is also complicated MACD service and maintenance of customer clusters are expensive MPLS between HCS DC and customer sites is expensive and also has long lead time Typical VPN solution requires additional CPE at customer site, and it is hard to manage and maintain BRKCOL Cisco and/or its affiliates.

10 What is HCS Shared Architecture?

11 What is HCS Shared Architecture (HCS-SA)? HCS-SA is Deployment Model offering lower TCO o Optimized DC Resource Usage (multiple customers sharing same UC cluster) o Minimum Operation Cost (streamlined customer onboarding process and automation) o Low Cost for Site Deployments - OTT Access via MRA (device self-registration) HCS-SA is a Standardized Offer powered by Automation o Service Creation One Size Fits All (standardized offer w/ options) o Target Markets Commercial and Enterprise (>= 10 users in average) o Service Automation Powered by ASAP/Kurmi/VOSS4UC o Centralized Directory Service and Tenant Separation Enabled by Imagicle BRKCOL Cisco and/or its affiliates.

22 UDS Directory Search All Jabber clients connecting via Expressway will use UDS for directory search (assuming Unified CM IM&P deployment) TelePresence endpoints, DX series, IP Phones also use UDS directory search For the best contact search experience, all Enterprise Users should be imported into every Unified CM cluster s end user table Home cluster check box needs to be selected on only one cluster for each user BRKCOL Cisco and/or its affiliates.

23 Cisco Expressway Mobile and Remote Access Expressway Firewall Traversal Basics Enterprise Network DMZ Outside Network Unified CM Expressway C Firewall Expressway E Firewall Internet Signaling Media 1. Expressway E is the traversal server installed in DMZ. Expressway C is the traversal client installed inside the enterprise network. 2. Expressway C initiates traversal connections outbound through the firewall to specific ports on Expressway E with secure login credentials. 3. Once the connection has been established, Expressway C sends keep-alive packets to Expressway E to maintain the connection 4. When Expressway E receives an incoming call, it issues an incoming call request to Expressway C. 5. Expressway C then routes the call to Unified CM (or other collaboration services/applications) to reach the called user or endpoint 6. The call is established and media traverses the firewall securely over an existing traversal connection BRKCOL Cisco and/or its affiliates. All rights reserved. Cisco Public 23

Customer places order for the HCS-SA Service thru SP portal or thru Meraki Portal or thru SP sales team. SP gets notified of the order and using API s provisions the Meraki Device with necessary config ( DHCP/TFTP, VLAN etc) for specific phone ports on the Meraki Device). The IP address will be configured for readonly and will not be editable by the Customers. SP automates the creation of the HCS-SA VPN tunnel from the Customer Premise to the VPN Concentrator in HCS DC. SP provisions the HCS SA for the Customer in the HCS DC. Customer plugs in phone and registers to the HCS-SA cluster thru the Dedicated HCS VPN Tunnel and starts making and receiving calls. BRKCOL Cisco and/or its affiliates. All rights reserved.
