Connecting IP phone w/ MG90

#1

Has anyone on here had experience setting up a SIP phone on an MG90? The model I am trying to connect is a “Verizon yealink t46G”. However, I am getting registration errors each time I connect the phone. The MG90 is working as should…DNS is up and I am able to browse the internet just fine with a laptop connected. Is there some kind of port I need to enable or networking rule I need to enable for the phone to get out and register??

Any help would be greatly appreciated!
