Voicemail Office has enabled our non-profit organization to run smoothly and efficiently while giving it the professional image of a large, multi-department office. I love the ability to easily transfer calls between extensions, even when one of us is away from our desk! Voicemail Office has also helped to consolidate our messages by allowing us to receive and store voicemail and faxes in one place. I highly recommend their services!

In practice, most businesses are simply handling this on a case-by-case basis since COVID is a temporary problem. Most home networks can handle the extra load as long as the employee makes sure that other latency-sensitive traffic, like gaming or video streaming, is kept to a minimum during the hours when they need to talk. If some home routers develop problems, IT staff simply build a queue and handle those one at a time. Sometimes they'll be able to access the router remotely with the employee's permission, sometimes they'll have to walk that employee through configuration steps to fix the problem. Sometimes the employee will just have to live with it unless the company springs for a new router or a higher bandwidth tier from the employee's ISP.
