Group 700 devices

Will our group 700s be affected by cipher changes for Zoom? Please see the email below from Poly that was received.

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

“Dear Valued Customer,

We are writing to inform you about an upcoming change to the Zoom CRC (Conference Room Connector) service.

In our continuous effort to maintain high security standards, we have identified certain weak cipher suites supported by Zoom CRC for Session Initiation Protocol (SIP) connections using Transport Layer Security (TLS) that must be retired from service. The discontinued cipher suites have been identified as vulnerable to potential security risks and are no longer recommended by industry standards. Removing them will help enhance the security of your data transmissions and help protect the confidentiality, integrity, and authenticity of your communications. As a result, the following Zoom CRC SIP TLS cipher suite changes will take place as part of the next Zoom CRC software release, scheduled September 29, 2023.

Discontinued ciphers

  • DHE-RSA-AES256-GCM-SHA384

  • DHE-RSA-CHACHA20-POLY1305

  • DHE-RSA-AES128-GCM-SHA256

 

Supported ciphers

  • TLS_AES_256_GCM_SHA384

  • TLS_AES_128_GCM_SHA256

  • TLS_CHACHA20_POLY1305_SHA256

  • ECDHE-ECDSA-AES256-GCM-SHA384

  • ECDHE-ECDSA-AES128-GCM-SHA256

  • ECDHE-RSA-AES256-GCM-SHA384

  • ECDHE-RSA-AES128-GCM-SHA256

  • ECDHE-ECDSA-CHACHA20-POLY1305

  • ECDHE-RSA-CHACHA20-POLY1305”

Hello @ihaveissues  ,

 

welcome to the HP Poly community.

 

You have posted in an incorrect section and your post has been moved by a volunteer. It has been moved to a section more suitable for your request.

 

I would suggest you contact our Partner Zoom on this as it is them who are making the change. 

if you struggle contact the support organisation in your region. Details are in my signature. 

 

Best Regards

 

Steffen Baier
