2.2 Configure PPP 4 (PSTN)
It will be necessary to configure PPP 4 as an outbound interface as the default is for the interface to accept incoming calls. Then ISP configuration will be added.
Navigate to the following location:
Configuration - Interfaces > PPP > PPP 0 - 4 > PPP 4 > Standard Scroll to the bottom of the page and click “Load dialling defaults”.
The PPP 4 configuration needs to be configured to be “always on” and have a power up delay of 60 seconds to allow the ADSL connection to come up and be the primary connection. The interface will also be configured for use with an ISP, enter the details as shown in the tables below.
