Skype for Business, Dialing Terms of Service and NCOS Codes

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.
