The problem there is that VoIP traffic is much more sensitive to network bumps and potholes than most general office traffic. That translates to garbled conversations, difficulty connecting over Wi-Fi, or (worst case) dropped and lost calls. If your business is small and your network is essentially contained in one or two wireless routers, then your configuration and testing headaches might be fairly easy (though still there). For medium and larger networks, these tasks can be complex and time-consuming, which translates into added cost in terms of man-hours.
eVoice provides businesses with all the features they need to deliver a seamless communication process with customers.

If you've got a VoIP system, however, then you've likely got one of the aforementioned softphones as part of that service, and that's how most organizations are meeting the COVID challenge, as evidenced by a survey conducted last year by sister site, Spiceworks Ziff Davis:
