I can hear the modem sound on the other end of the line. What is the problem?
Check with the hotel management if the phone system is digital or analog. If the phone system is digital you will need to have a special adapter to connect. The only alternative is to request access to a fax line (fax lines must be analogue to function). Check for pulse or tone dialling. If the phone system is analogue you are safe to connect your modem. Before attempting to dial check if the phone system uses pulse dialling or tone dialling. You can easily check by picking up the phone and dialling one digit. Listen for clicks (pulses) or tones. This will tell you whether to select pulse or tone dial in your software. Ensure that the line is fully connected between the jack and modem. If you are not getting any audible modem/line noise or you cannot hear your modem “handshaking”, use your telephone handset to call the modem number to ensure that it is a modem line.
