A lot of people have a phone on their desk that can be reached directly from outside by dialing a specific number. Most people are not normally public-facing employees, so why would they waste their time with the whole "Thank you for calling, Smurfco. This is Sally, how may I help you?" I think a standard greeting would be poor OpSec for the NSA, since people could discover their unpublished numbers by dialing all the numbers.
