I have a client with a wifi calling drop issue. I'm trying to assign static IPs to these devices to see if it resolves the issue. I know with other network systems, I had to contact the mobile device carrier -- whether ATT, T-Mobile etc-- and find out the right ports to forward to as well. I assume the same would be the case with ruckus unleashed. In sum, I want to know how to assign static IP addresses to iphone 8 mobile devices in ruckus unleashed to resolve wifi calling drops. Thanks.
