All Nww.net access numbers function on a digital roll over and you should never get a busy signal.
If you do receive a busy signal, please make sure your computer has been shut down & restarted recently.
You may even try to dial the access number with your regular phone. If you get a fax type tone sound, then the number is working and your computer must need restarting. If you get a busy signal with your regular phone, then Nww may need to troubleshoot the system.
(Just call 281-479-3154 and report the trouble.)

Note: To check and be sure that a number is not long distance for you, just use
dial the number and listen for a modem tone... This means it is not long distance.
But, if you get a voice request to put a 0 or a 1 before the number, then it is probably long distance.
