Hello everyone!

I'm going to buy for my home-business a SIM based LTE Router which is the TP-Link N300 4G LTE Telephony TL-MR6500v V1 but i have a question i could not find answer yet.

If i want to connect few IP telephones over this router, can i connect a ethernet cable through the Phone Port (in the router) to a Switch and then from the Switch to the IP Telephones with ethernet cable?

(Could not find my Routher on the list so the model is TP-Link N300 4G LTE Telephony TL-MR6500v V1)
