Hierarchical Navigation

We endeavor to make our Cisco TelePresence products interoperable with all relevant standards-based equipment. Although it is not possible to test all scenarios, the testing on which this data is based covers most common functions of the listed endpoints and infrastructure.

The following pages describe the software releases that were tested for interoperability with Cisco TelePresence products. The results are grouped by product range. It is not possible to guarantee that all the models listed in the Product(s) column have been tested with the specified software release, although to the best of our knowledge we believe that all such models are interoperable with the associated software release. The absence of a device or release does not imply a lack of interoperability.

Product(s) Software releaseComments

No unresolved issues found.
Cisco TelePresence Content Server S5.3 Tested H.323 and SIP. No issues found.
Cisco TelePresence System 500-37, 1000, 1100, 1300-65, 3000, 3010, 3200, and 3210 1.7.2

Tested Unified CM to Cisco VCS SIP and Unified CM to Cisco VCS H.323.

  • A known encryption issue with interworking to the CTS causes calls to appear encrypted on the IP gateway when they should not appear as encrypted.
  • Video on CTS appears frozen at low bandwidth.
  • Low bandwidth SIP calls result in frozen video on the CTS.
  • If encryption is disabled on the CTS-3000/CTS-500, calling via an IP gateway that requires encryption results in a half-encrypted call. This issue is resolved in Cisco VCS Version X7.2.
Classic 6000 E5.3 PAL

Tested H.323 and H.323-SIP interworked.

  • Encrypted calls at bandwidths greater than 768 kbps between a Tandberg Classic endpoint and Cisco TelePresence MCU may result in various video problems.
  • RTCP timestamps from the Cisco TelePresence MCU 5300 Series are unreliable.
T1 TelePresence, T3 TelePresence TC5.1.0 No unresolved issues found.

Cisco Unified IP Phone 9971 9-2-3-27

Tested SIP and SIP-H.323 interworked.

  • G.729 calls do not work correctly when interworked.
  • Interworked calls can take a long time to connect. These issues are resolved in Cisco VCS Version X7.2.
Cisco Unified Video Advantage 2.2.2.0

Tested Unified CM to Cisco VCS SIP and SIP-H.323 interworked.

  • Transcoded H.323 calls do not work due to an issue on the gateway side.
Unified IP Phone 7985G 4.1(7)

Tested SIP-H.323 interworked and Unified CM to Cisco VCS SIP.

  • A VCS issue currently affects this endpoint when interworked.
  • The endpoint may not be able to decode video from the IP gateway when H.263+ is negotiated. The endpoint sends repeated Fast Update Requests but does not decode the key frames sent by the gateway in response.
  • DTMF in interworked calls does not work (the gateway does not support DTMF over KPML).
  • H.323 transcoded calls exhibit sub-optimal behavior.

Product(s) Software releaseComments
Room 200 4.7.18

Tested SIP and H.323.

  • Transcoded calls result in video from a CTS endpoint appearing vertically stretched with H.264 and horizontally stretched with H.263+.
  • Transcoded H.323 calls cause purple blocks to appear on this endpoint.
  • Encrypted SIP calls are not supported between the gateway and this endpoint.

Panasonic

Product(s) Software releaseComments
KX-VC300 2.30

Tested SIP and SIP-H.323 interworked.

  • Encryption and 1080p resolution is not supported between this endpoint and non-Panasonic equipment.
  • Most transcoded H.323 calls fail.
  • Video corruption is observed on video from this endpoint.

Polycom

Product(s) Software releaseComments
HDX 4500 3.0.3.1-19040

Tested H.323 and SIP.

  • The IP gateway cannot receive H.261 video during SIP calls because the endpoint does not advertise H.261. This does not affect functionality if other codecs are enabled.
  • The endpoint cannot send simultaneous H.263+ main video and H.264 content. All other codec combinations work.
  • Delay in opening the audio channel can result in early part of voice prompt not being heard at the endpoint (CSCtz01271)
  • Using only the Siren 14 audio codec is not supported in some cases (when the codec is not advertised by the endpoint).This does not affect functionality if other codecs are enabled. (CSCtz21120)
QDX 6000 4.0.2

Tested H.323 and SIP.

  • If this endpoint has encryption set to “when available”, it advertises encryption as “required” rather than “optional”. Consequently, if encryption is disabled on the IP gateway then calls to or from this endpoint will fail.
  • Hissing audio was experienced when using G.711 and G.722 during encrypted calls.
  • H.261 and Siren14 are not advertised by this endpoint when using SIP.
ViewStation 6.0.5 Tested H.323 and H.323-SIP interworked.
No issues found. (One issue was detected in initial testing but is now resolved.)
VVX 4.0.1.13681

Tested H.323 (non-transcoded and transcoded) and SIP.

  • H.323 non-transcoded. In one call scenario, when this endpoint is set to H.263, the IP gateway receives H.263 CIF but transmits H.263+, which the endpoint fails to decode. The other endpoint in this scenario was a Cisco TelePresence System Codec C40. Other codecs were unaffected.
  • H.323 non-transcoded. When this endpoint is configured for H.264 and G.722.1C or Siren14, the call fails to connect. The other endpoint in the call was a Cisco TelePresence System Codec C40.
  • H.323 transcoded. When only G722.1 Annex C or Siren 14 is enabled, with the endpoint running version 5.0.1.11086, calls to the IP gateway auto attendant work, but if the dial plan is set to dial the endpoint directly or the endpoint is dialed through the auto attendant the call fails.

Scopia XT1000 02.05.0208

Tested H.323 and SIP. The following behavior was observed for this endpoint:

  • Encrypted SIP calls are not supported.
  • Squashed video is sent by the endpoint when using H.263+.
  • If the endpoint is set to “Favour Motion” it sends approximately 17 fps video.

Audio between the IP gateway and this endpoint is not supported on interworked calls if the endpoint Audio Mode setting is MPEG4 Audio or Auto.
PCS-G50 2.72

Tested H.323 and H.323-SIP interworked.

  • In some circumstances in H.323 calls, no audio is heard on this endpoint.
  • Encrypted interworked calls with this endpoint are not supported. (CSCtz12733)
PCS-HG90 2.22.00

Tested H.323 and H.323-SIP interworked.

  • This endpoint is HD only and cannot be used in transcoded calls except in audio-only mode.
  • Encryption is applied only to part of the call path.
PCS-XG80 2.31.00

Tested H.323 and SIP.

  • Some endpoint issues were observed with negotiation of G.728 and G.711.
