I have a PBX system w/ two ISP’s. One is dedicated for VoIP and the Gateway is managed and the VoIP calls can only go out that route. The other is just regular ISP. But, I know we can use the second one for regular internet, since we hooked up a laptop to the gateway and ran a speedtest.net. I have a second Trunk (Digium) which can use any ISP/Route since its a cloud based setup. We use this as our failover if our Dedicated VoIP line goes down. But, I’m thinking of using the Digium trunk more, but I want to confirm that its using the Dedicated VoIP ISP when possible.
I’m not overly familar with Wireshark, I’m wondering if there is a way from the CLI to figure out which ISP the ourbound route is using.
