No Dialling Tone When I Pick Up Hand Set.

1. Unplug all devices from every phone socket, including your modem, telephones, fax machines, pay TV boxes and EFTPOS terminals.
2. If you have a different phone service (e.g. mobile) available, try calling your own home phone while nothing is plugged in. If it rings normally, skip to step 3.
3. If you hear an engaged tone or a recorded voice saying the number is not available, please call us on 13 22 58 for further assistance.
4. Plug a standard phone handset directly into the phone socket (without a filter), and then attempt to make a call. If you were able to make a call, skip to step 7.
5. If you have more than one phone socket in your home, plug your phone handset (without a filter) into each of those sockets and attempt to make a call. If you have a dial tone and can make a call when your phone is plugged into one socket but not another, there may be a problem with your home's internal wiring.
6. Using a different phone handset, repeat steps 2 and 3. If a different phone handset gives you a dial tone but the original phone handset doesn't, then the original handset may be faulty.
7. If you can't make a call on either handset, please call our Support Team on 13 22 58 for further assistance.
8. If you can now make a call, plug your phone handset into the phone socket with a filter and attempt to make a call. If you can't make a call, that filter may be faulty.
9. Plug your other devices back in one at a time and attempt to make a call after each new device is plugged in. Always start with any devices that are plugged in with a filter.
10. If you suddenly can't make a call again, then the device you've just plugged in may be faulty or interfering with your phone service, or it may be plugged in with a faulty filter.

I recommend replacing a filter or device if it is faulty, or adding a filter to a telephony device if it didn't already have one.

Thanks
