Most likely it's Motorola Solutions providing the hardware, although there's probably some 8A business playing middleman to collect their guaranteed contracting dollars.
Everyone likes to bag on the big contractors, and not without reason, but if you really want to raise your blood pressure, look at the rules, laws, and entitlements regarding 8A contracting. We've had to deal with middlemen that took 10% simply to get a fax from the gov't, and pass it on to the hardware vendor (also on the GSA schedule), who then shipped directly to the gov't. 10% of a quarter million dollar order for receiving a fax, and faxing it onward, because as a small business who meets all the contracting requirements, they're guaranteed a certain amount of federal payola, simply for existing.
There was a lot of joking about forming our own businesses, BOFH style (translation: our fax machine and office is co-located at the local pub), to cash in on that gravy train.
