7 Architecture improvements New Skype cloud for improved call set up and control.New gateway connects Skype cloud to Lync Online for signalling and call control.Uses Lync’s federation access architecture that routes to both v1 and v2 clouds.V1 connectivity will continue to exist as traffic gradually increases on V2 connectivity.
10 Call connectivityAll AV calls flow through the same federation environment set up in v1Lync SIP/SDP signalling is terminated at the Skype Cloud edge and translated into Skype proprietary protocols and vice versaLync to Skype CallsAV calls are forked internally to both v1 and v2 clientsMediation server supports only AudioNew Lync Gateway services all v2 calls.Skype to Lync Callsv2 clients will route calls through v2 Skype Cloud > Lync federation environment > Lync clientv1 clients will route calls through v1 Skype Cloud > Lync federation environment > Lync client
15 Technology improvements Direct media connectivity between Lync and Skype clientsSILK has been ported over to Lync desktop client. Coming to other Lync clients soon.SILK will currently only used in Lync-Skype Interop CallsG.722 and G.711 remain on the list of common codecsVideo using H.264 SVCMedia connectivity using ICE - ICE v19 support added to Skype clientAlong with STUN\TURN for NAT traversal
16 SILK CodecLync-Skype Connectivity v2, SILK WB with a target bit-rate of 36 kbps will be the default audio codec for Lync-Skype callsSILK integration for Lync desktop client was released Lync 2013 CU4 update (Nov 2013).Older clients will continue using 64kbps.

21 H.264 UC Config Mode 0In this UCConfig Mode, one reference frame is used to constitute the single layer bitstream. Each P frame uses the immediate previously reconstructed frame as the reference frame.
22 H.264 UC Config Mode 1If the maximum frame rate of the source is 30fps, then Layer 0, or the base layer, has frame rate of 15fps. Layer 1, or the enhancement layer has frame rate of 15fps too. Decoding of Layer 0 and Layer 1 results in 30fps.
23 Enterprise NAT Traversal Mechanism Stun/Turn/ICE SIP uses the source and target IP addresses to establish a session. Network Address Translation (NAT) modifies IP addresses as packets transit onto the public internet and thereby renders the INVITE invalid. STUN, TURN and ICE resolve such session/NAT issues.InternetInternetRouterDMZ❷❶EdgeICE ClientICE Server❸❶ Host Candidate – Likely to fail❷ STUN Candidate❸ TURN Candidate – Edge Relay
25 Ensure your enterprise can federate with Skype!
26 Enabling Lync Skype Federation If your enterprise is already configured to connect with Windows Messenger via PIC, you are already set up to federate with Skype!Achieved by provisioning via the PIC (Public Instant Messaging Connectivity) systemValid for both Lync Online and On-prem.Full details at:Same steps for both audio only federation (current GA) and future video enabled calls
