Setup Groups and Users
A group is similar to a deparment, name the different groups you would like to create. Each group can have its own extension and/or phone number where calls ring to ALL users within that group. Indicate the desired extension for each group and whether you want to have a dedicated phone number for each of them.
List all the users in the account with their email addresses. They will receive their credentials to that email.
*NOTE: each extension needs to be unique, a group and an user cannot have the same extension.
