Microsoft will no longer have its own certificates presented by anynode during the establishment of a TLS connection signed by the Baltimore CyberTrust Root CA, but rather by the DigiCert Global Root CA. The transition to certificates issued by the new Certificate Authority began at the end of August 2023.
On September 19, 2023, Microsoft will conduct another 24-hour test for this purpose. During this process, all Microsoft SIP endpoints will be transitioned to certificates leading to the “DigiCert Global Root G2” Certificate Authority. All anynode customers using one or more Microsoft Teams Direct Routing trunks and not using version 4.8 or above or who have not manually installed a certificate should anticipate certificate validation errors and a disrupted connection on September 19. The final transition to the new Certificate Authority (CA) will take place on October 3.
Ensure that the additional DigiCert certificate has been added to the Trusted List in the Teams Node. To ensure connectivity both before and after the transition, both Root CA certificates must be listed in anynode’s Trusted Certificates list.
Starting from version 4.8, anynode handles this automatically through the Migration Assistant. The new DigiCert root certificate will be automatically migrated to the list of trusted peer certificates. With anynode 4.8, you don’t need to take any further action. We strongly recommend users of older anynode versions to manually add the new root certificate to the Trusted Peer Certificates to prevent unnecessary outages. You can download the required DigiCert Global Root G2 certificate directly from the DigiCert website.
Further information is available on our anynode homepage, detailing where you can view and edit the list of Trusted Peer Certificates in the anynode frontend.
