Hi @IBN ,
Regarding Dial Plan, as you mentioned, it's currently not supported in Policy packages and doesn't have the option of "Group policy assignment" either.
And for Voice Routing Policy, although it can be added in to policy packages, as indicated in the warning message you shared above, a policy package with Voice Routing policy is currently not supported to to be assigned to a group.
Given this, you may consider assigning them to bulk users instead as a workaround. For more details, you may refer to: Assign a policy to a batch of users.
