1. Auto Attendants and Call Queues are supported in a pure-cloud environments. Hybrid environments such as the one seen in this walkthrough are not officially supported
2. Creation and set-up of auto attendants requires either getting or transferring existing toll or toll-free service numbers. In addition, toll-free service numbers require PSTN Consumption Billing to be setup. In this walkthrough we will acquire and use toll-free service numbers for our Auto Attendant and Call Queues but note that none of this will be callable as we do not have PSTN Consumption Billing setup.
With the above, lets begin the walk-through.
