The elegance of LinkedPhone’s cloud-based virtual phone system is how easy it is to configure complex tasks. First, tap the keypad button you’d like to configure. Second, tap the function you would like to perform. Third, provide a name for your call menu option. If you’re setting up call routing, simply tap the people you’d like to route calls to. It’s really that easy. The images below illustrate how easy it is to set up a call menu option that routes calls to select team members.
If you've still got a legacy voice system, meaning an on-site PBX with analog phones, then your only real COVID response will be call forwarding to your employees' home phones. That may or may not be acceptable to your employees, especially since these days many of them won't have an analog phone available, which means you'll need to do your forwarding to a personally-owned mobile phone.

You can no longer have a lousy phone system that lacks compelling features. Modern phone systems offer redundancy to direct calls to cell phones in the unlikely event of an internet connection outage. Whether you’re selling the best office phone for a small business or international enterprise, a modern VoIP solution is within reach.
For one, be sure to understand QoS (mentioned above). This means going beyond understanding the concept and moving to how the networking equipment in your office -- or your employees' home offices if you're still at that stage -- can actually implement QoS. Most business-grade networking hardware will be able to handle QoS in more than one way, so testing which method will handle voice traffic more smoothly in your environment is important.
