Might this be an artefact of cellular carriers being fixated on revenue protection of their inter carrier rates. Are they (wrongly) assuming a public IP might be a grey market termination risk onto their networks?<br>

I had a similar issue with wifi calling on O2 in the UK. it<br>
worked on some wifi but not others. After pressing O2 support<br>
for quite some time they admitted "you're on commercial IP space<br>
which we don't support" but would say no more.<br>
<br>
After a little puzzling I realised the working wifis were<br>
NATed to 1918 so I added NAT to one that wasn't working and the<br>
phone registered OK for wifi calling. The address it was NATed<br>
to was the same range so it appears their test is for 1918 space<br>
on the client.<br>
<br>
I'm not saying HULU is the same, I've never has access to it,<br>
but companies cook up some wierd ideas of what is accepable for<br>
client access. I've still got no idea why having a public IP makes<br>
it unnaceptable to make phone calls where their coverage is poor.<br>
