11. Lync/Exchange Calendar Integration
Unlike Skype, Lync is tightly
integrated with other Office
applications
So a calendar appointment
becomes a Lync meeting with a
single click.

With version 2, we now use standard NAT traversal protocols, Signalling is encrypted with TLS and
media uses sRTP directly between callers. We’ve standardized Codecs between the clients and have
added Video !!

21. Technology improvements
Direct media connectivity between Lync and Skype clients
• SILK has been ported over to Lync desktop client. (other soon)
• SILK will currently only used in Lync-Skype Interop Calls
• G.722 and G.711 remain on the list of common codecs
• Video using H.264 SVC
• Added support for FEC
• Media connectivity using ICE - ICE v19 support added to Skype client
• Along with STUNTURN for NAT traversal

33. Built on the same service as Call Park
Orbit range - globally unique numbers allocated for parking calls, can start with * and #.
Specific number ranges assigned to pools.
No call retrieval authentication - any user or integrated PBX phone can retrieve a call.
User Experience
User dials an extension to retrieve the call while ringing
Orbits can be flagged for Group Call Pickup - Users are enabled by being assigned an orbit number.
Private Line, Delegation, Teamcall, Simulring, RGS, and Personal Contact calls not allowed to be picked up.
Clients
2010 and higher to pick up; mobile, analog phones, and PBX phones not supported.
Administration
SEFAUtil tool is needed for Group Call Pickup user configuration.

37. Availability Q2, CY2014
disclosed and
demonstrated to the
general public in the
Lync Conference keynote
on February 18th
MICROSOFT CONFIDENTIAL – INTERNAL ONLY

38. Contacts/Presence
• Remain consistent with phase 1
• Skype* and Lync users can add users & view
presence
Sessions
• Chats, voice (Silk) and Video (H.264)
• Encryption with TLS and sRTP
• NAT Traversal with Stun/Turn/Ice
Not included:
• Select Mobile clients (Skype)
• Multi-Party Calls
• Other modalities including data sharing
With phase 2, we are adding video between Lync & Skype users along with
encryption through TLS for signalling and sRTP for media.
* Skype users require MSA authentication

40. Lync Server is not directly authenticating the user. It is relying on a trusted source (ADFS) to handle authentication on its behalf
Other authentication-type examples:
“Our security policy mandates all solutions utilize other forms of
authentication aside from a traditional username/password”
“Our users don’t know their passwords”
#

41. 1. Windows Phone Lync client asks the Lync
Server to sign-in. Server responds back with
authentication types
2. Client understands it needs to contact an
ADFS server in order to authenticate. Client
sends request to ADFS, ADFS validates the
need.
3. Client presents auth cookie to Lync Server
for a WebTicket; then used WebTicket to
request a Lync Cert and successfully signs
in.

42. Targeted for Q3 CY2014

49. New content focused on deployment & user experience

52. Android Tablet Client
• Announced to be available around summer time

53. Android Tablet Client
• Announced to be available around summer time

55. JLync
• Demo during keynote on healthcare website

56. JLync – Javascript Lync
• Enable Lync integration on websites
• Audio/Video/Screensharing, most likely with browser plugin
• Javascript Object Model for using UCWA
• Delivered using CU for Lync Server 2013 “when it’s ready”
• Rumor it will be called UCJA (UC Javascript API)
• “WebRTC” Ready

58. Announcements @ Lync Conference 2014

60. During Keynote
• Demo call between Lync client & Legacy Tandberg VTC

61. Why would we need Video Interop Server
• Signaling / Control Channel
Different SIP “dialects”
• Media Stream / Codecs
Lync: H.264 SVC Mode 1
VTCs: H.264 SVC Mode 0

62. How it works
• Signaling / Control Channel
Mediate between different SIP implementations
• Media Stream / Codecs
Re-packetization of Lync’s Mode 1 stream to Mode 0
