Interoperability Database

Warning - In preview mode

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.

Cisco TelePresence Server software version 4.4

Show data for version: 4.44.34.2(4.23)4.2(3.x)4.24.1 4.14.14.03.13.0(2.48)3.0(2.24)3.02.3(1.55)2.32.2(1.54)2.2(1.48)2.1(1.18)


Interoperability testing often requires interworking from one signaling/call control protocol to another. The following table lists phrases that are used to briefly describe the call paths that were tested for each interoperability scenario. The explicit call paths in the table place the endpoint first and the TelePresence Server last as a general convention. References to ‘TS’ mean either TelePresence Server behind Cisco TelePresence Conductor or TelePresence Server on its own.

Product(s) Software releaseComments
Cisco TelePresence Content Server (TCS) 6.2

Tested SIP.

  • Audio only calls to a TCS will not be recorded.  ·             
  • Reporting of media packet loss from the TelePresence Server to the TCS may be unreliable.    
  • TCS is unable to enter a conference via a PIN protected URI due to Conductor dropping the DTMF relay message.
Cisco TelePresence IX5000 and IX5200 8.1.2

Tested CUCM (SIP).

  • An endpoint issue may result in a large number of RTCP authentication error messages in the TelePresence Server logs (CSCuz37894).
Cisco TelePresence SX10 CE8.2.2

Tested SIP.

No issues found.

Cisco TelePresence SX20 CE8.0.1

Tested SIP.

  • At very low bandwidths audio prompts may not play correctly. · 
  • When joining a multistream conference the standard background lobby screen picture drops away to show a grey lobby screen before the conference video displays. This does not affect functionality.
  • If the endpoint is making a multistream call and is put on hold and then resumes, the call will become a single stream call.
Cisco TelePresence SX80 8.2.0

Tested SIP. ·        

  • At very low bandwidths audio prompts may not play correctly.       
  • After presentation has been sent, the main video channel may not recover to full bandwidth. ·        
  • When joining a multistream conference the standard background lobby screen picture drops away to show a grey lobby screen before the conference video displays. This does not affect functionality.
  • If the endpoint is making a multistream call and is put on hold and then resumes, the call will become a single stream call.
Cisco TelePresence System EX60 TC7.3.5

Tested CUCM (SIP).

  • Under heavy packet loss conditions, video from the endpoint may freeze as viewed by other endpoints.
Cisco TelePresence System EX90 TC7.3.5

Tested SIP.

No issues found.

Cisco TelePresence System TX9000 6.1.12(4)

Tested CUCM (SIP).

No issues found.

Cisco TelePresence Video Communication Server (VCS) X8.6, X8.7

In some call flows invoking the VCS B2BUA for encryption, calls may drop after some time if presentation is shared. This is most likely to affect immersive or multistream calls. This issue is resolved in X8.8.1, see CSCvc47502.

DX70 10.2.5.207

Tested CUCM (SIP).

No issues found.

DX650 10.2.5.207

Tested CUCM (SIP).

No issues found.

Cisco Jabber for Windows 11.6.2

Tested CUCM (SIP).

  • Due to an endpoint issue, at very low bandwidths presentation from the endpoint will be shown as black video to other participants.
