This is usually a modem error message.
1. Make sure no other pieces of software are using the modem, if so, close the applications, and possibly reboot the
computer and try it again, making sure those applications are still closed when the machine reboots.
2. If you just added an init string, or new drivers for the modem, remove the init string, and rollback to the older
3. You could try uninstalling/reinstalling the modem.
