Re: 8 bit sound
Depends if it's carrier grade QOS managed VOIP or VOIP over random public Internet.
My own phone service (real geo numbers) is using VOIP on a fixed wireless link, but only as far as my ISP's voice switch. So Fax and analog modems usually work. Your mileage with a 3rd party VOIP supplier over the ordinary public internet will vary with your connection jitter and packet loss. Unlike gaming, or person to person chat, latency isn't an issue.
