But it's for sure to me that the single uplink is correct.
Later you revealed you have an IP phone (I'm guessing here) and maybe your installer used this rather smart setup to keep your network costs down. While I think the speed gain would be non-existent you could wire up a second LAN just for the phones. I wouldn't do that but the client is always right.

At my work, we have 2 modems to handle our phone calls and internet usage. My question is if our network is properly setup. The main line comes in and splits off to the two different modems. The modems both plug into the router and then the router goes of with one line to the switch. My question is, should we have more than one line going off to the switch since there are two modems. The router is supposed to see what's coming in and route it properly. But if there is only one line going out of the router to the switch, would that cause slowdown and issues? See pic below.
