I have a Skype for business account that won't connect when i am at home. I can use a laptop at home that won't connect, take that laptop to work and it connects just fine. when it does not connect, it references Microsoft KB2566790. that mentions adding DNS records, etc. i kind of get what it is suggesting, i have no idea where to add them. is this a regular problem with Skype and Verizon? what is the solution to this to get this working?
