14. New Lync 2013 features with Interop implications: Using Pool FQDN instead of individual machine FQDN for cert & connection checking. Failover Routing and four second socket connection timer from Mediation. DNS Load Balancing Support outbound from Mediation to SIP peer. Dual Stack IPv4/IPv6 Unsupported: Bypass on v6 & Standalone v6 on Mediation egress Passing Referred-By and History-Info from Mediation to Peer (dropped the other way) Resiliency enhancements for trunking – bidirectional OPTIONS, peer routing to backup pools Gateway / SBC SBAIP-PBX SIP Trunk E911 SP Pool FQDN for CertYesN/AOptional N/A Fail-over RoutingYesN/AOptionalYes DNS LB SupportYesN/AOptional N/A IPv4/IPv6 SupportOptional SIP Header SupportYes Optional M:N RoutingYes

15. Supported: Lync 2010 Mediation with Lync 2013 pool Functional at 2010 level of capability Great for customers upgrading to Lync Server 2013 with minimal impact 2013 Mediation needs to interoperate with 2013 qualified infrastructure Timing: When will X be qualified with Lync 2013? Interop testing starts when the product is completed

16. RCC interconnects with a legacy PBX Provides click-to-call using PABX handset & informs binary phone presence in Lync Does NOT work with Enterprise Voice – client can be either RCC or EV Interop with the PABX uses ECMA standard TR/87 for CSTA over SIP RCC is still supported in Lync 2010 and Lync 2013 P2P video calling for RCC-enabled users supported as of March 2012 update Split Audio / Video continues to remain deprecated for future There is no interop program for RCC (and there never has been….) The protocol is stable with little to no investment on either PABX or Lync side Generally available from major PABX manufacturers through their presence engines RCC is a legacy feature that ties the customer to disadvantageous PABX economics

17. SBCs recent addition to UCOIP qualification ACME Packet, AudioCodes, NET/Sonus Equivalent testing to Gateways & IP-PABXs Useful when customers are: Already is using an Enterprise SBC (typically ACME) for multi- vendor protocol interoperability SIP Trunking deployments to support bypass. Not qualified for firewall traversal / edge Lync edge offers support for greater range of modalities
