What are the charges for long distance calls made from Skype for Business?
Beginning 7/1/17, domestic and international long distance charges are included as part of the centrally funded IT service suite. Long distance calls are no longer billed to the specific telephone number that made the calls, regardless of whether they were made from Skype for Business or the legacy Centrex system.
More information can be found on UC, Long Distance Telephone Services.
