Limitations Identifier Description release. CSCtz69665 In previous releases, the 'purge selected' button to delete selected conferences on the MCU did not work for certain localisation packages (e.g. Russian). This is resolved in this release. CSCua09848 In previous 4.3 releases, the MCU API did not trigger an update through participant.enumerate when the active speaker in the conference changed. This is resolved in this release.

Interoperability Call path phrase Explicit call path description CUCM to VCS H.323 Endpoint <--SIP--> CUCM <--SIP--> VCS <--H.323--> MCU. CUCM to VCS SIP Endpoint <--SIP--> CUCM <--SIP--> VCS <--SIP--> MCU. Note: Unless otherwise stated, CUCM version 8.6(2a) and VCS version X7.1 were used in the interoperability tests. Endpoints This section lists interoperability issues with endpoints, by manufacturer.
PAGE 6
Interoperability Equipment Version Results circumstances H.264 is used in preference to H.263+. Cisco Unified IP Phone 9-2-3-27 9971 Tested CUCM to VCS H.323 and CUCM to VCS SIP . No issues found. The MCU 5300 Series only supports Cisco Unified IP Phone 9971 running version 9-2-3-27 or later. Cisco Unified Personal 8.5.4.196096.2.83 Communicator Tested CUCM to VCS H.323 and CUCM to VCS SIP. No issues found. Cisco Unified Video Advantage 2.2.2.0 Tested CUCM to VCS H.323 and CUCM to VCS SIP.

Interoperability Polycom endpoints Equipment Version Results Polycom HDX 4500 3.0.3.1-19040 Tested H.323 and SIP.  The Polycom HDX 4500 is unable to decode video or content sent by the MCU in aspect ratios of 1600x1200 and 800x600. (CSCts46398 / Polycom reference: VIDEO-90136)  Using only Siren 14 audio codec with this endpoint is not supported. However, if the MCU does not apply this restriction, the parties will successfully interoperate using a different audio codec.  Using only H.

Interoperability Sony endpoints Equipment Version Results Sony PCS-G50 2.64 Tested H.323 and H.323 to SIP interworking.  Encrypted interworked calls with this endpoint are not supported. (CSCtz12733) Sony PCS-1 3.42 Tested H.323 and H.323 to SIP interworking.  Audio between the MCU and this endpoint is not supported on interworked calls if “Audio Mode:” setting on the endpoint is set to either “MPEG4 Audio” or “Auto” Sony PCS-HG90 2.22 Tested H.323 and H.323 to SIP interworking.
PAGE 9
Interoperability Equipment Version Results  G.722.1 Annex C is not supported between the MCU and this endpoint. (CSCtz21139) Panasonic KX-VC300 2.30 Tested SIP and SIP to H.323 interworking..  Encryption is not supported between this endpoint and non-Panasonic equipment.  1080p resolution is not supported between this endpoint and non-Panasonic equipment.  Delay in opening audio channel to MCU can result in early part of voice prompt not being heard at the endpoint.
PAGE 10
Updating to 4.3(2.30) Infrastructure This section lists known interoperability issues with infrastructure components. These may manifest themselves as issues with a particular endpoint or series of endpoints. Equipment Version Cisco TelePresence Video Communication Server (VCS) X7.1 Results    When interworking between H.323 and SIP, the VCS does not perform offer/answer correctly for G.729 codecs. This can manifest itself as a lack of audio on interworked calls that use G.729 codecs.
