Phantom was hit by a high bill because >>of busy signals. He told me that: If voice-to-voice, they will not charge >>busy signals; If modem-to-modem, they will charge busy signals. >Since the calling modem is silent until the answering modem >sends its pilot tones, how could the phone company know >whether a busy signal was an attempted modem or voice >connection? And even if tones were sent, the phone company would have to be eavesdropping on the line to determine if it is a modem or voice. This sounds like it would be illegal. -- Tom Lowe tel@hound.ATT.COM or att!hound!tel 201-949-0428 AT&T Bell Laboratories, Room 2E-637A Crawfords Corner Road, Holmdel, NJ 07733 (R) UNIX is a registered trademark of AT&T (keep them lawyers happy!!)
