Lightning Case Studies: Implementing Modern Enterprise Communications
Across Industries
All capital projects in an Enterprise must be justified using financial, operational, and technological
criteria. This includes implementation of an Unified Communications system. In the Customer Case
Studies session, a panel of customers will present a synopsis of their reasons for selecting sipXecs /
openUC for their Unified Communications Systems and whether or not their objectives have been met.

Challenge – Bring Pythian’s telecom system up to a level
where it can support the aggressive corporate growth
plans, and provide end-users with excellent voice quality
along with a feature rich voice platform.

6. Lightning Case Studies: Pythian 6
>Key Requirements
•Scalability for growth

7. Lightning Case Studies: Pythian 7
>Issues
•Pythian aggressive growth plan will put stress on the current single server design
•Current architecture built and developed by previous team and current teams knowledge is limited
•Architecture leads to poor call quality in areas that have poor data connections
•Architectures Single server design could lead to failure
•No redundancy or regional distribution
•Lack of UC software has lead to the use of multiple chat clients, video chat clients and no
presence capability
•No Voice Conference security on bridges
•Old hardware set for refresh

26. Lightning Case Studies: Selventa 26
>Selventa is a 40 person biotech company
>One main office with distributed personell across three continents
>We do business in the US, Europe and Asia

27. Lightning Case Studies: Selventa 27
>Selection Criteria:
>Functionality
•More modern phone system, easier integration with other phone systems (e.g. mobile, Skype, etc.)
•Better conference room speakerphone quality
•Conferencing functionality built in – reduce/remove our reliance on other audio-conferencing
solutions
>Cost
•Not looking for cost reduction but happy to get one, can’t be more expensive
>Ease of management
•One IT Ops manager – has to be simple and easy to manage, low effort
>Reviewed mostly hosted VOIP solutions

28. Lightning Case Studies: Selventa 28
>Deployment process
>Tested server with a couple of desk phones and Bria prior to company
deployment
>Rolled out openUC in the afternoon for almost seamless switchover (Dec 20th)
•Interestingly enough – most users opted for softphone (Bria client) only
•Linux users had trouble getting a SIP-client softphone setup
>Almost everyone has cell phones so company phone system is less critical to
business operations

29. Lightning Case Studies: Selventa 29
>Call quality is generally higher
•Still having some problems with echo using softphone
>Audio conferencing works very well, but still working on education/awareness
>Some growing pains with the new Amazon hosting option
•Some DoS attacks have caused problems
>Overall less expensive than previous system
>Mgmt overhead vs. previous PBX system is higher but indications are it will
reduce to <= PBX as deployment matures with increased functionality

30. Lightning Case Studies: Selventa 30
>Deployment, lessons learned, summary
>Successful switchover
>Softphones are still quite challenging for most users – though they like the
option of having their phone with them at all times
>Love being able to set up a desk phone and ship it to field locations for them
to plug in and use
>Conferencing lines are simple and easy to use
>More angst and effort involved in selection and planning than actual
deployment

40. Lightning Case Studies: Lafayette College 40
>Fitting into Infrastructure & Skills
•sipXecs was supported on RHEV
•'yum install sipxecs'
•Leverage existing Linux skills
•Not a magical black box

41. Lightning Case Studies: Lafayette College 41
>Deployment: Adding VOIP to Network
•3 PRIs from provider into Definity G3
•4 PRIs out of the Definity into AudioCodes
•IP out of Audio Codes into OpenUC
•All SIP and RTP traffic goes through SBC
•Isolation leads to good security

42. Lightning Case Studies: Lafayette College 42
>Deployment: Selecting Pilot Users
•ITS; we were the first to go
•Picked departments who use phone often:
>Development and Alumni Relations
>Athletics
>Communications
>Public Safety
•Met secretaries from these departments:
>Invited them to coffee break
>Asked them how they use phones
>Showed them OpenUC features
•Invited them to joint training session
•RoncDid same day place and set

43. Lightning Case Studies: Lafayette College 43
>Evaluation: 1 year into 3-year project
•Athletics & Development report time savings
•Some cost savings so far (retiring old PBX)
•Students get experience on real code
•Students using Bria/OpenUC in class:
> Each student meets 4 times with WA
> Half of these will be over Video Conferences
> WA will be available for questions over IM
>3 & 4 best: Mission of the college is education

44. Lightning Case Studies: Lafayette College 44
>Lessons Learned
•Make sure place/set vendor will do requirements gathering
•Whiteboard and ask questions until you're convinced that implementation details are correct (we
did this, it paid)
•Find the right spot to insert OpenUC into the existing PBX for minimal interruptions
