ChallengesInteroperability solved with media gatewayAdapt different SIP implementation of each vendorNumbering and SIP headers compatibilityDiversion on Lync, and History header on PBXReuse current infrastructure:Lync client as an extension of the PBXCurrent systems (Alcatel, Exchange, CERN specific tools)SecurityUsers, servers, phone systemRedundancyLync provides clustering (but no mirroring)17

ChallengesCompetences in two different groupsLync, Exchange: IT/OISTelephony, interconnection, special services: IT/CSSupport for different OSLinux: lack of audio/video support for Lync


PlansSoftphone Lync Go to production beginning of next yearVoice mail Migrate users from current Alcatel system to ExchangeFederation with other institutesFree phone calls, availabilityOther features are availableCallpark, Location, Response groupLync 2013Federation with SkypeXMPP gateway integrate with Google Talk, etcVOIP from mobile devices


SummaryWe gained experience in managing the systemMore features can be implementedThe key was to integrate it with current systemsTelephone, e-mail, phonebookCollaboration between peoplePeople doesnt like changes, butVery good feedback once using the system


Thank you!
