Cisco Telepresence Interoperability
As of today, Cisco does not have any qualified solutionOCS 2007 R2: in processLync: ask Cisco/Tandberg
Cisco/Tandberg planned interop through their gatewaysVCS gateway for signalingTandberg “Advanced Media Gateway” for media transcoding
Need both to get HD video
Two more VCS (control, expressway) to work across firewall

IP-PBX InteroperabilityPain points in OCS 2007 R2
Interoperability via Direct SIP (OIP qualification)Very broad range of PSTN gateways, Direct SIP to IP-PBX
However, in R2 Direct SIP requires routing media through Mediation Server
Not a significant problem for central sitesBut difficult in branches:
Requires Mediation Servers in branches and/orMedia tromboning (hairpin through the WAN to Mediation Server in central site)
![Page 20: EXL317. High quality video in every desktop Improve the meeting room experience Embrace and Lead Interoperability.](https://reader038.fdocuments.in/reader038/viewer/2022103005/56649dd95503460f94acee29/html5/thumbnails/20.jpg)

Removes need for media transit via a serverSignaling continues to transit through Mediation
B2BUA: security demarc, interop…
Media goes directly from Lync client to next hop (gateway, IP-PBX)Quality optimization (latency reduction, codec selection, media resiliency)
Based on location of Lync clientBypass only occurs if client is “local” to next hop
G.711 direct – optimized for LAN-like conditions; SRTP supported
When client is not “local”, media goes through MediationCodec optimized for WAN using per session CAC; RTANB over internetMediation provides audio healing
Enables “lightweight” Mediation (collocation with FE, SBA)
Lync 2010: Media BypassWhat it is and benefits
![Page 23: EXL317. High quality video in every desktop Improve the meeting room experience Embrace and Lead Interoperability.](https://reader038.fdocuments.in/reader038/viewer/2022103005/56649dd95503460f94acee29/html5/thumbnails/23.jpg)
“Always Bypass” in “Global Settings”Treats deployment as a single site, requires good connectivityMutually exclusive with Call Admission ControlWill always bypass to trunks enabled for bypass
“Use Sites and Region Configuration”Leverages topology information in Lync from CAC
Uses Region/Sites definition, requires a “Bandwidth Policy Profile”Associates unique Bypass ID with each Region/Site
Uses dynamic (real time) client locationClient IP address Bypass ID associated with client’s locationGateway address (for media) Bypass ID of the gateway’s location
Comparison of the IDs, bypass if the two IDs match
Lync 2010: Media BypassHow it works – two approaches

Inbound calls (to Lync)Mediation receives invite; IP address of media gateway in SDP
Potentially different from centralized call management (signaling) IP
Mediation computes gateway Bypass ID, puts it in SDP, forks invite to clientsClient makes bypass decision
Outbound calls (from Lync)Client puts its Bypass ID (from inband) in SDP, sends to MediationMediation finds gateway, determines gateway Bypass ID
Uses representative (“alternate”) media IP if configured, or uses IP associated with GW FQDN if not (signaling IP used for media – single site)
Mediation Server compares, call is bypassed if matches

Centralized IP-PBX with multiple sitesIP-PBX centralized in HQ for signaling and call control
Mediation talks to centralized instance
Local media gateways in branch sites (ex: Cisco ISR with MTP)Want to bypass media to local gateway when Lync is in the branch site
Lync supports media bypass in multiple sitesDefine regions and sites in network topology (same as CAC)Define (virtual) media gateways in topology builder
Associate representative media IP in site to each media gatewayDepending on specific IP-PBX requirements, different listening ports
Establish appropriate routing on both systemsIP-PBX unaware of Lync dynamic location; suggest routing to local trunk
Media Bypass – Multiple Sites, Centralized SignalingWhat’s different

Takeaway
Integrating natively with IP-PBXs canEnable a low cost Proof of ConceptProvide calling between migrated and non-migrated usersAllow for long term coexistence with existing IP-PBX starting to take advantage of Lync
Native integration with media bypass enablesCPE-less deployment of Lync in branches coexisting with existing IP-PBX, using existing equipmentKeeping much more of the media local, including in centralized multisite topologies
