That's VoIP i'm afraid. If it has an echoey hollow sound to it, you won't be able to remove that in all likely hood. The best you can try to do is put a high pass and a low pass filter on it, and roll the top and bottom end of it so that it sounds more like an AM telephone interview for effect. Most of the legible content is between 1.6k and 6k, with an emphasis in the 2.5 to 4 k range. Be careful with 4 k..can get harsh pretty quick. Trial and error. No magic bullets for this.
