This page contains Network Class of Service (NCOS) codes that describe restrictions that can be placed when dialing telephone numbers from Skype for Business.
NCOS settings are account/user specific and are requested by the Pinnacle Department Manager (PDM).
NCOS settings apply to Enterprise Voice enabled Skype for Business accounts only. Common-Area Phones (CAP) have NCOS settings too.
All NCOS allow dialing to 911 for emergencies. None of the NCOS settings are able to dial 900 (per-minute fee/toll) numbers.
