15. Cisco Intercompany Media Engine The Cisco Intercompany Media Engine (IME) represents the first time that companies can conduct secure, high-quality, voice and video telephone calls across the internet - using their existingtelephone numbers - without the need to re-provision or replace currently deployed infrastructure.

16. Intercompany Boundary-Less Communications Among Business Partners and Customers Cisco Intercompany Media Engine Submitted to IETF: Accelerating business value through standardization Enterprise video telephony and high fidelity wideband audio across companies Enables innovative collaboration capabilities and applications to be shared among partners Secure, efficient network utilization with reduced costs Utilizes SIP and PSTN coexistence Multiple levels of security plus voice spam blocking Effortless for users and administrators Easy to use: Self learning Consistent user experience Company A AtoZ, Inc. Company B Borderline, Inc.

17. PSTN PSTN Gateway PSTN Gateway Cisco Unified CM Cisco Unified CM Internet Extranet Enterprise B Enterprise A Moves Calls from PSTN to Direct SIP Trunks Automatically SupportsExisting Phones & Numbers Worldwide Unlimited Scale Low Provisioning – Self Learning Saves Costs Secure Works with or without Service Provider Automated Spam Blocking Brings Full UC Experience QoS Insurance via PSTN Internet or Extranet

19. Enterprise IME Servers then:

20. Form worldwide P2P network

21. Publish phone numbers they “own” to P2P network

22. First call to a number goes over the PSTN

23. PBX in both enterprises send call info with start and stop time to their IME Servers. This forms a shared secret

24. Later, the IME Servers performs call validation to servers in P2P network that claim to “own” the number

25. Provides proof of that previous PSTN call went to the IME server that claims to “own” the numberIME Internet/ Extranet IME IME IME Enterprise A Enterprise B PSTN

27. The next call placed to that phone number is a Secure Business to Business call over the IME SIP Trunk instead of PSTN.

28. Seamless Fallback to PSTN if QoS problems detectedIME Internet/ Extranet IME IME IME Enterprise A Enterprise B PSTN

29. How Cisco Intercompany Media Engine Works Session ManagementEdition Unified CM SessionManagement Edition PSTN Company A Company B IntercompanyMedia Engine IntercompanyMedia Engine IP Network Firewall Firewall PBX 1. Employee at Company A places a DID voice call to colleague at Company B 2. At completion of call, respective Session Management Edition systems send call details to Cisco Intercompany Media Engine 3. Company A’s IME initiates validation with Company B’s IME and returns a SIP route and validation ticket to Company A’s Unified CM Session Management Edition, via IME 4. Next time employee at Company A calls colleague, Unified CM Session Management Edition places an SIP call over the IP network and sends the ticket in the header to Company B’s firewall to enable the rich media session to securely pass

30. Cisco IME Security built-in from ground-up All IME traffic is encrypted - media and signaling (TLS+SRTP) Encryption at perimeter firewall - no need to turn on security in your entire enterprise End to end secure media if both phones are in secure mode Dial plan information in the Cisco IME network is hashed. 128 bit node id’s stored not numbers. False number advertisement prevention Spam protection - blocks unwanted calls right at the firewall Protection against Denial of Service Attacks on CPU, memory. and bandwidth Spam

31. Combining Three Powerful Technologies To provide the first mechanism to move calls from the PSTN and securely send them over any IP network DHT: PSTN: SIP: For Scale (testimony of Scale is Skype with > 500 Mill Users and > 50 Mill users online at a time) For validation of phone number ownership For its flexibility and feature delivery

Cisco Intercompany Media Engine Deployment Components Cisco Media Convergence Servers (MCS) for Cisco IME Server with HP and IBM Software equivalents Large 7845 up to 40,000 users Small 7825 up to 10,000 users Cisco ASA 5500 Series Adaptive Security Appliances (ASA): 5510, 5520, 5540, 5550 and 5580 . Version 8.3 Cisco Unified Communications Manager 8.0 Cisco ASA 5500 Cisco Unified CM 8.0

36. Notifies UCM of need to fall back

37. Provides TCP/ (TLS) Conversion

38. Provides RTP/SRTP Conversion

39. Ticket Validation (Using Shared Secret between ASA and IME Link Server)Cisco IME Server Sits in DMZ Participates in P2P Network Provides Call Validation Sends Route updates to UCM Cisco Unified Communications Manager 8.0 Receives updated routes from IME Server; updates dialplan. Publishes DIDs to IME Link Server Executes PSTN Fallback Enrollment Server hosted by GoDaddy.com Certificate Authority for IME Server Certificate IME Server 8.0 UCM 8.0 / SME 8.0
