ASUS TeleSky User Manual
Why does the phone not ring when a normal call or
Skype call comes in?
The phone ringer may be off or too low to hear.
Adjust the ringer volume.
Cable deployment may be incorrect or your PSTN
phone line is not properly connected. Check all
cable connections and run the device set-up
diagnostic utility on the support CD.
The ASUS TeleSky utility may not be running.
Launch both the utility and Skype to ensure a Skype
dial tone is heard.
You may not be logged into Skype. Log in to your
Skype account.
