If when you try to dial out any number you are receiving audio message from Microsoft Teams saying "Call not allowed due to your organization's settings" then review the following as a possible cause:


local based routing is enabled once PreventTollByPass is enabled on user.  
assign a TeamsCallingPolicy to users to AllowCallingPreventTollByPass 
Since the Prevent Toll By Pass may be blocking the call then change the policy to AllowCalling
