Are your not-quite-broadband customers attached to some PBX that will handle it and send G.711 to your carriers? That's going to cost some CPU or dedicated transcoding hardware. Will your providers accept G.729 and transcode for you? Is there a cost for it? Or will your carriers blindly throw your G.729 at their LCR and hope something sticks?</div></div>
