Will cipher changes for Zoom affect Poly Group 700 devices
Will Poly group 700s be affected by cipher changes for Zoom? Please see the email below. -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- “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.
