Configuration Description
In some cases, more FXS, FXO or BRI ports are needed as available on one SmartNode for certain applications. This conifg example shows, how to stack two or more SmartNodes, achieving more channels / ports.
The idea is to let the "Master" SmartNode handle all calls. It communicates with the SIP server and distinguishes calls to the slave SN over the second ethernet port (LAN) in case all TDM channels are occupied. The service hunt-group is in charge of this. ISDN ports, 0/0 on both SmartNodes are used for clock sync, while a PSTN line is plugged.
IP network which connects the two SmartNodes is 192.168.20.0/24. There is no SIP call authentication between the two SmartNodes. Please make sure you set and replace all values which are commented as below with #.
