Fairly sure that call will go something like this...
OP> "Dear Hyperoptic, what is the static IP I've been given?"
H> "www.xxx.yyy.zzz"
OP> "Ok great. How long does it take to take effect?"
Then Either
H> "Its there now, just power cycle your router"
or
H> "Our networking team will have actioned this by hh:mm. We'll drop you an email when done."
