My phone has no dial tone

• If the phone is a Gigaset or softphone: this is normal. These phones don’t have dialtones. Use them as a mobile phone i.e. enter the number to dial and then press send or dial. If you can’t dial out then check that you have an Internet connection on your computer.
  
• If the phone is a analogue phone plugged into an analogue telephony adaptor (“ATA”): Check that the phone is plugged into the ATA. Check that all cables on the ATA are plugged in. Check that the network cable from the ATA plugs into a network port. Check the lights on the ATA and confirm that the power and Internet lights are on. Check you have an Internet connection on your computer. Plug the network cable that leads from the ATA into a network port that is currently used by a working computer. Unplug the power from the ATA for 5 minutes and plug it back in again.
  
• If the phone is a VoIP hardware phone: Check that all cables on the phone are plugged in and that the network cable is plugged into the port on the phone labelled “WAN” or “SW”. Check that the network cable from the phone plugs into a network port. Check you have an Internet connection on your computer. Plug the network cable that leads from the phone into a network port that is currently used by a working computer. Unplug the power from the phone for 5 minutes and plug it back in again.
