WELCOME TO THE CALLTOWER FAMILY! To get started with your Implementation, you will want to prepare your network and users for a successful Microsoft Teams implementation. We rely on the CallTower Connect platform to automate the roll out of Microsoft Teams. For Direct Routing Customers, CallTower Connect will build the Direct Routing Link and assign phone numbers to your users. For Operator Connect Customers, CallTower Connect will synchronize your emergency locations and upload numbers into those locations. For Direct Routing customers CallTower Connect utilizes a service account with Global Admin,Teams Admin and Skype for Business Admin Roles to build the Direct Routing Link to CallTower, Once the initial configuration is complete Global Admin role can be removed and it will continue to manage phone numbers for user accounts and resource accounts. This is automatically included for our CSP Microsoft licensing customers on either Direct Routing or Operator Connect.
There are a few required steps you will need to take to prepare your network for Microsoft Teams. The following guide will help you determine which changes may be needed on your firewall and network configuration for the best possible experience when using Teams for voice. It will also provide an overview of troubleshooting tools in the Teams Admin Portal. Please provide your Networking and Administration teams with these links as soon as possible.
