While using our Workers module will help you get the most out of IO Phone, not everyone using IO Phone uses the Workers module. It is not required that you use the workers module to use IO Phone, but at the same time, we need to record numbers so that we can appropriately forward your calls. Consequently, we've created a settings page specifically for those that do not use the Workers module.
On the IO Phone Worker Numbers page, you can specify up to 3 different forwarding numbers that you want to use with IO Phone. You do not have the option to name these numbers, unfortunately. That is something that you can only do when using our Workers module. Once these numbers are defined, you can use them in building groups, setting ring schedules, and more.
