No Dial Tone Your phone should be plugged to the Phone 1 port of the ATA. A common mistake is to plug it in the Phone 2 port, leaving Phone 1 empty. Phone 2 should be used only if there is a second line or a fax line. To check that, pick up your phone's receiver of handset and press Talk or OK. If you have a single phone and Phone 2 lights up, you have plugged your phone jack in the wrong port. Have you used a proper RJ-11 jack (commonly called a telephone jack)? If you have, you also need to check whether it is well fitted in the port. It will work only if you hear a 'click' when plugging it in, else it stays loose. There is a little tongue on the side of the jack that ensures proper 'clicking' and fitting of the jack to the port. That tongue very often easily gets torn off, especially with frequent removal and insertion of the jack. If that happens, have the jack replaced. If the RJ-11 cord is an old one, there are chances that it is not transmitting data as it should, due to the effects of temperature, deformation etc. Have the cords replaced. They are quite cheap, and many ATA vendors ship two of these in the package. The problem can also be with your phone set. Try connecting another phone and check if you get a dial tone. Also, if your phone set is connected to the wall jack (PSTN) while being also connected to the adapter, you will not get a dial tone. This can furthermore be damaging to the equipment. A phone used with a VoIP adapter should not be connected to the PSTN wall jack, unless so specified. Absence of a dial tone can also be the result of bad connection with the Ethernet or Internet connection. This will be the case if the Ethernet/LAN connection light is off or red. To troubleshoot your connection, see the next step. At times, resetting your system (adapter, router, modem etc.) can help solve a problem.
