our Addtrust/Usertrust certificate chain is changed in Sectigo. Sectigo is not a trusted root CA in a Polycom VVX phone. I've tested it with a Softwareversion UC 22.214.171.1247 but connecting to a Skype for Business environment is not possible anymore. I know I can upload the chain, but we have multiple customers with lots of phones. For now we will replace our certificate with a supported chain. Do you know if Sectigo will be added as a trusted CA?
This is the news item from Sectigo:

that would be great! Also in the 5.9 channel would be nice, cause the 'old' VVX versions (like my test 500) can't run v6 firmware. I'll test as soon as the new firmware is released.
