Surface Hub PSTN calling options?
This is probably as much an Office 365 question as a surface hub question, but I'll start here: We have surface hubs set up using room accounts in Office 365, and they currently have an E1 license assigned. If I want to enable people to dial in to conferences using the surface hub, do I just need to add the pstn conferencing option to the surface hub account? What if I wanted to make outbound calls from the hub? Can I do that by just upgrading it to an E5 license and adding the PSTN connectivity option? If so, does adding E5+PSTN to just one (or a few) accounts affect the rest of our accounts/O365 tenant or have any other consequences that may not be obvious?
