I can register my SIP zoiper account from my home wifi and LTE. At work on the WiFi I can not register, but if I turn off WiFi the SIP account will register on LTE.
I watched the CLI and I think I see the problem, but don't quite understand how to fix it and maybe someone can help. Here is what I get.

It looks like when I register on LTE it shows my actual IP address and then pokes me and deems me "reachable".
