How It Works - Cisco IME High-Level Call Flow

Internet/Extranet
PSTN
• All participating enterprise configure Cisco IME and their phone numbers
• Enterprise IME Servers then:•Form worldwide P2P network•Publish phone numbers they “own” to P2P network
• First call to a number goes over the PSTN
• PBX in both enterprises send call info with start and stop time to their IME Servers. This forms a shared secret
• Later, the IME Servers performs call validation to servers in P2P network that claim to “own” the number
•Provides proof of that previous PSTN call went to the IME server that claims to “own” the number

How It Works Cisco IME Call Flow
• Upon successful validation, the originating side IME Server securely pushes learned route to the PBX
• The next call placed to that phone number is a Secure Business to Business call over the IME SIP Trunk instead of PSTN.
• Seamless Fallback to PSTN if QoS problems detected

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

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