Posted by Markus Zeier, Last modified by Daniel Lizaola on 19 December 2017 01:43 PM

SN46X8 SmartWare SWR 6.X Sample configuration SmartNode connected as trunk gateway between a SIP network and PBX with 4 S0 port.

Copy and paste the below config in to a text editor.
Replace all the values as described on the lines starting with a #

The Port S0 slot 0 port 0 is configured as fall-back and sync-port. It is configured in the user mode and should be connected to a PSTN. The ports slot 0 port 1 to 4 are configured as net and should be connected to a PBX. Not all the ports have to be connected
