SCIFs can be anywhere they are needed provided they are secure. There is one in congress. We had one at a civilian contractor job I worked at. They aren't necessarily military either. Lots of government agencies have and/or create various levels of classified data. Even the DoE (energy - not education) has Top Secret.
The TS VOIP doesn't seem out of the ordinary either. Remember these guys would be talking to a bunch of government agencies and people - including our allies. Some of those contacts would likely be via secure phone - especially FBI/CIA and places like Australia or some of our embassies.
