Editor's Notes
- Some introductions to get started: I’m Alan Percy, Senior Director of Product Marketing for TelcoBridges and today’s event moderator. Joining us again is Luc Morissette, Director of Customer Support and one of the founders of TelcoBridges. Luc, thanks for being a part of today’s event. Before we begin, a little housekeeping: As a live event participant, you’ll have the opportunity to interact with today’s speakers and hope you do pose your questions and comments on today’s topic using the Q/A panel. To pose a question or comment, open the Q/A panel by clicking on the box in the upper left of your screen. We’ll cover your questions toward the end of the session. We’ve found that some attendees may need to adjust the webinar View Options to see the full slide on your screen. If you are not seeing a full slide, move your mouse to the top of the webinar window and a View Option selection will appear – choose an option that best fits your screen. Also, today’s event is being recorded and all those that have registered will received a link to the recording for on-demand playback. We hope you share the link with your co-workers and others that would find the discussion valuable. And we’re glad to have you, our attendees, with us today and encourage you to use the opportunity to interact with our speakers by posing your questions and comments.

- First a little background: As network architects in service providers and large enterprises plan their migration to cloud infrastructure, one network security element plays a critical role and needs special treatment - the Session Border Controller. At the crossroads of real-time voice and video traffic, SBCs are tasked with providing protection against DDOS attacks, facilitating NAT traversal, providing topology hiding, resolving interoperability issues and much more.

- Can be deployed in various platforms. TelcoBridges functions is deployed in software that can run on these 3 platforms. FreeSBC is Platform Agnostic and provides flexibility to deploy solution best fit your needs. Extra slides for more details. Hardware platform specifications. -> freedom of choices that fits business needs. Bare metal be Intel CPU with Intel NIC. Performance would depends on hardware. For deployment in virtualized computing platform, Vmware and KVM OpenStack are supported. Roadmap with more hypervisors. AWS Support is coming soon
