I an issue where at least one user (limited test base) has the wrong sip information so is always offline. The details show sip:firstname.lastname@example.org instead of sip:email@example.com.
Here is an example of the account that is not working:
And here is one that is working:
I have checked the AD account where the user is being synced from and the Office 365 account to make sure that the sip information looked right there and it does, unless I'm not looking in the right places.
I also have the issue where the Skype Chat picks the wrong user to connect too. This is already a reported bug: https://support.freshservice.com/support/discussions/topics/316700
