Check the phone number the user is dialling is correct. Also ensure that they don't have "Use area code and dialling properties" ticked with the POP number. Check do they need to dial 9 for an outside line, if so are they dialling it? Check also for telco services such as Call Waiting and Call Answering, if necessary get the user to contact their telco for info on how to temporarily disable them. Get the user to dial the POP number from a phone handset and see what they get.
In 99% of cases this will cure it but if not :
Check that the POP the user is dialling is not down or busy.
If the POP is in working order get the user to dial a normal phone with their
modem and see does it ring. If it rings then try this modem string :
ATZX0
If the phone did not ring then it is likely that the modem is damaged in some way. Sometimes this error occurs if the modem is a British Model and the user is not using the British to Irish adapter. Check if the modem is compatible with the Irish phone system by typing ati7 in Hyperterminal. If it says that the modem is British or another country then make sure that the user is using the correct converter.
