Hello everyone.

In our company we have purchased this router as an update plan for our network devices. We have configured the router so that it takes static addressing with the information provided by our ISP.

The incident we are presenting is when registering IP phones. Our configuration is very simple due to infrastructure issues: We have a network cable connected from the ISP router to the TPLink RT using the main WAN port. From the TP Link router to the SW using the WAN/LAN port. From each port that the SW offers us, we connect the IP phones. Finally, a cable that goes from the IP phone to each computer.

The new router does not have any special settings, such as VLans, bandwidth control, etc. The old router (NetGear Orbi) also has no special settings. With the old router, the phones are able to register on the network of our telephone provider (Spectrum).

For this router model (ER605 V2) do I need to make any special configuration? I have tried disabling the ALG option but it doesn't work. It should be noted that I am using Omada's software-based controller.

Thank you very much in advance.
