Windstream is not opposed to AT&T or any traditional telco's migration from TDM to IP-based services, but it is calling for regulators to ensure that it and other competitors can get last-mile circuits for equivalent prices. Serving as both an ILEC and CLEC in the markets it serves, Windstream has built out an extensive fiber and copper network, but as it extends its services to more multi-site customers, it can't reach every location it needs to serve by building out its own network.
