1 BBTelsys and Secure SIP Calling Providing Solutions that Work in the Real World

2 BBTelsys LLC Background of a New Venture Broadband Telephony Systems established as an early VoIP telephony carrier in 2004 by Art Hale BBTS purchase in Michigan investors recruited for new venture New management structure – Roland Scott, CEO New Operational investments – Latest technology, New NOC, existing + new partners – Competitive low-costs, open systems, superior quality – Responsiveness to customers New Strategy/Re-branding – Commercial Differentiators Reseller Distribution Strategy

3 BBTelsys Re-launch Completion of operation infrastructure – Lower cost – Flexibility for unique services December 15, 2008 official re-launch of company

4 Speaker Background CEO Investor Application Software + High Tech Exec Business and Market Consultant New Products Development Professor Entrepreneur VoIP “just another IP application” (and a little more…a world of possibilities)

5 Who WANTS Secure Calling Barack Obama (and others) – national security, public safety Utilities – operational security, homeland security Legal – protecting confidentiality, negotiations Large Manufacturers – competitive and HR info Medical – privacy (Hippa), medical records and messaging Financial – deal secrecy, confidentiality

6 How did BBTelsys get started? Working with Ingate since 2003 (early adopter) – Putting the tools in place to secure networks Respect for securing the network – Don’t let VoIP be a tempting target for hackers – The business customer expects % up-time. It is a “mission critical application”. – Well managed IP infrastructure is essential. Interaction with Customers – Asking the Customer “What If” – Our strategy is to search for differentiators – Secure calling is a niche but significant unmet need

7 What Ingate Brought to Our Attention Signaling and Media flow separately TLS/SRTP (Transport Layer Security/Secure Real Time Protocol) could provide the right and sufficient encryption for the dynamics of VoIP application (although not widely used) – Low Overhead – High number of small packets – Dynamics of both TLS (on signaling) and SRTP (media) creates a high level of difficulty to crack decoding encryption

8 Flexibility of Ingate SIParators Decrypt/encrypt both TLS and SRTP streams to and from the PBX Decrypt/and then re-encrypt for end-to-end solutions Pass the media in its encrypted state without decrypting

9 What’s Wrong with Most Data Encryption Technology Developed for data, long packets The more complex the better Time delay doesn’t impact use High Overhead Produces Delays Which Interrupts or Downgrades Voice Quality

10 What Devices Can Use TLS Ingate’s Edge Devices TLS aware phones – Polycom – Aastra – Snom

11 Where are Customers Vulnerable The customer is most vulnerable to espionage at his internet connection Most existing PBX’s do not allow for encryption

12 Confidentiality on the Internet PSTN IP-PBX Mobile user BBTelsys TLS/S RTP User authentication (HTTP Digest) – Used SIP Signaling encryption (TLS) – Not widely used RTP Media encryption (SRTP) – Not widely used Internet Home/Hotel user

13 Testing the Concept (A major utility) IP-PBX TLS Internet TLS/ SRTP BBTelsys Carrier Switch PSTN IP Phone TLS/SRTP aware

14 TLS – End-User/Carrier Results Quality of Call Maintained, no noticeable influence or delay Approximate Bandwidth Overhead appears quite low (but has not been measured?)

15 BBTelsys is Open for Business BBTelsys offers TLS Test Calling Today – SIP Trunks – Hosted Plans The Opportunity for a Reseller or End-User – Secure calling is a differentiator – Major accounts interested – Separate yourself from the competition with BBTelsys

16 Future Secure Calling Developments Secure solutions for the Mobile Worker – Current wireless networks frequently unsecured. – a major worry for security conscious – Opportunity initially with softphones to provide similar security – Future solutions on smartphone with fixed-mobile convergence running VoIP phone (ala President’s Blackberry?)
