Is the voice assistant's number a landline or a mobile?
It depends on the country. Each country has its own number types available for voice (landline, mobile or toll-free) and some only have one, so you can’t always choose.
How to request it
When you activate the voice assistant you reach the number setup screen, Voice Setup. On the “Request New” tab you fill in “Business type” and “Additional notes”, and the team contacts you to complete the setup. If you need a specific number type, say so in “Additional notes”.
If your country has no numbers of its own available, only that tab shows, with a note that an international alternative can be offered.
In some countries you first need to complete a verification with company details and documents: the same screen tells you.
