Combining VoIP with the traditional telephone network
Some service providers use the traditional telephone network (PSTN) as a backup solution for your VoIP connection. This way, you can still make calls over the traditional network if the VoIP service is down - for example, if your Technicolor TG589 router is powered off.
Please note, if you’re not connected to the traditional telephone network, emergency calls will not be possible when your internet connection is down or your Technicolor TG589 router is powered off.
Check if your Technicolor TG589 router has a PSTN port on the back panel. If your router has a PSTN port, connect this port to the Phone output of your filter or splitter using an additional telephone cable (RJ11) that may be part of your package.
