Are there any anonymous VOIP providers for USA phone numbers? One can that make receive voice calls, SMS, have voicemail, etc. Ideally something like http://voip [dot] ms but is not KYC and accepts monero.
Yes and no. Although there are no available VOIP providers that have all the features you have listed, but you can achieve that by customizing pre-existing ones. You have to set up a custom VOIP solution using Monero and USA numbers. You can use a SIP server, Monero wallet, and API integration to create a fully anonymous and automated system.
