Nope, youre right, playbook is the right term. Got it mixed up with chef.

Since no one has mentioned it yet -

If you haven’t tried setting Synapse up with the ansible playbook you should. It’s almost push-button and has 1:1 voice calls by default. Setting up group voice from there is a bit challenging, but the playbook has a section for it as well if you’re willing to try.

Edit: cookbook - > playbook

Just to emphasize, this is the correct answer
