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

PSTN<br />PSTN<br />Gateway<br />PSTN<br />Gateway<br />Cisco<br />Unified CM<br />Cisco<br />Unified CM<br />Internet<br />Extranet<br />Enterprise B<br />Enterprise A<br />Moves Calls from PSTN to Direct SIP Trunks Automatically<br /> SupportsExisting Phones & Numbers<br />Worldwide Unlimited Scale<br />Low Provisioning – Self Learning<br /> Saves Costs<br />Secure<br /> Works with or without Service Provider<br />Automated Spam Blocking<br /> Brings Full UC Experience<br />QoS Insurance via PSTN<br /> Internet or Extranet<br />
  18. 18. How It Works - Cisco IME High-Level Call Flow<br /><ul><li>All participating enterprise configure Cisco IME and their phone numbers
  19. 19. Enterprise IME Servers then:
  20. 20. Form worldwide P2P network
  21. 21. Publish phone numbers they “own” to P2P network
  22. 22. First call to a number goes over the PSTN
  23. 23. PBX in both enterprises send call info with start and stop time to their IME Servers. This forms a shared secret
  24. 24. Later, the IME Servers performs call validation to servers in P2P network that claim to “own” the number
  25. 25. Provides proof of that previous PSTN call went to the IME server that claims to “own” the number</li></ul>IME<br />Internet/<br />Extranet<br />IME<br />IME<br />IME<br />Enterprise<br />A<br />Enterprise<br />B<br />PSTN<br />
  26. 26. How It Works Cisco IME Call Flow<br /><ul><li>Upon successful validation, the originating side IME Server securely pushes learned route to the PBX
  27. 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. 28. Seamless Fallback to PSTN if QoS problems detected</li></ul>IME<br />Internet/<br />Extranet<br />IME<br />IME<br />IME<br />Enterprise<br />A<br />Enterprise<br />B<br />PSTN<br />

How Cisco Intercompany Media Engine Works <br />Session ManagementEdition<br />Unified CM SessionManagement Edition<br />PSTN<br />Company A<br />Company B<br />IntercompanyMedia Engine<br />IntercompanyMedia Engine<br />IP Network<br />Firewall<br />Firewall<br />PBX<br />1. Employee at Company A places a DID voice call to colleague at Company B<br />2. At completion of call, respective Session Management Edition systems send call details to Cisco Intercompany Media Engine<br />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 <br />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<br />
  30. 30. Cisco IME Security built-in from ground-up<br />All IME traffic is encrypted - media and signaling (TLS+SRTP)<br />Encryption at perimeter firewall - no need to turn on security in your entire enterprise<br />End to end secure media if both phones are in secure mode<br />Dial plan information in the Cisco IME network is hashed. 128 bit node id’s stored not numbers. <br />False number advertisement prevention<br />Spam protection - blocks unwanted calls right at the firewall<br />Protection against Denial of Service Attacks on CPU, memory. and bandwidth<br />Spam<br />
