Hello im testing the Hot Standby in my S100 but I have a question with the option Unilateral WAN Port the idea is to connect to both of my S100 the SIP Trunking services?
In my case, the ISP installs on-premise a router that has the SIP Trunk services this router has 4 ports.
So I need to connect both S100 WAN Ports to the router and enable the Unilateral WAN Port option and this will work when the MAIN S100 is down?
