I have a client with a new computer and an usb modem the system is a slim factor computer and cannot install an internal modem via pci slot.
We get a dial tone from the line that is plugging in to the computer and can receive / make phone calls with no problems.
The issue is when I dial the ISP it cannot dial out says No dial tone. I have replaced the modem 3 times all different brands.
I get this issue with 2 computers the client and my laptop witch works at my home on dialup with no problem.
I would like to know what could be the cause for this if possible the fix.
