DVG-N5402G/ACF Quick Installation Guide
Communication Using PSTN
Connect an RJ-11 cable to the Line port of the router and a phone jack. If the
router is connected to a PSTN line, an incoming call comes to the phone
connected to the Phone 1 port.
To configure outgoing calls, go to the VoIP / Advanced settings page.
In the PSTN options section, fill in the PSTN Routing Prefix field (enter
the prefix which you will use in order to access the PSTN line from analog
phones connected to the router).
