If you are talking about the DA prospect, you are incorrect to suggest that it is a carrier that is referenced in the 10-Q.
Here, instead, is what is said:
"The Company has successfully passed the testing phase with a national yellow pages provider and is now discussing commercial deployment and licensing terms."
Obviously, that is my emphasis put in there, but it is NOT referenced to be a carrier that does the yellow pages. Rather, it is a "national yellow pages provider." I so not believe that the provider is likely to be R.H. Donnelley (Dex), however, as its testing of a voice-enabled yellow pages DA was with a Toronto-based company as recently as last fall, per http://blog.searchenginewatch.com/blog/070905-105954
That is not to say it could not be R.H. Donnelley, but the other company seemed to have the position. Nonetheless, it is true that Qwest, ATT and Verizon dominate the yellow pages industry in the US (per Wikipedia), but to infer a carrier into the SEC filing would be precisely that, an inference. There simply is no such reference in the actual filing (unless I simply missed it, which is possible, I suppose).
