I have a VOIP service for my home phone through my previous internet provider. When I switched over to Koodo for internet I kept my previous wireless router and simply swapped the old modem with the modem Koodo provided. Yesterday my router stopped working and I setup the wireless router that Koodo provided me. I am able to connect all devices as expected but if if try and connected my VOIP hardware then the router will not work.
The setup is suppose to be modem → VOIP hardware → wireless router
This was the setup I had with my old wireless router and there were no issues. Is there a setting I need to make on the wireless router that Koodo provided in order to get this working?
