Making Calls from a
Hotel or Business PBX
Normally, your LAN+Modem card waits for a dial tone before dialing. In some
cases, however, a modem cannot detect a dial tone even when voice calls can be
completed. This problem can occur when:
■
Dialing into a standard telephone network using nonstandard dial tone
conventions
■
Placing a call from a country outside of the United States, where a different dial
tone is used
■
Dialing through a business or hotel PBX or a voice-mail system that indicates
new mail with a unique dial tone (travelers often find that hotel PBXs have
unique dial tones)
■
Using telephones (such as cellular telephones) that require you to press a
button before the dial tone can be heard
Try the following suggestions for restoring the standard dial tone:
