At that point, the Treasury Department said it would choose a vendor through the General Services Administration's framework of telecommunications contracts. But last September, the agency again put the TCE contract out for bid after deciding that the GSA's procurement programs wouldn't meet its needs.

Networx, the program that Davis wants the Treasury Department to use, will replace the government's existing FTS2001 telecommunications contract, which will expire next year.

The GSA is expected to award the main portion of the Networx contract next summer, choosing from among four teams of vendors that submitted bids in October.
