Pull out a GPS App on your phone and make sure you can actually read the
satellites from behind the window (I used 'GPS Test' on Android). We
had to install one of these boosters and were troubleshooting why the
damn thing wasn't working when I noticed that my phone GPS receiver was
working in rooms where the windows were open and not working in rooms
where the windows were closed. Building management didn't even know
they'd purchased the windows with RF film.

It might not be just a matter of getting the location. If they use the
1pps clock from GPS to calibrate an oscillator before they start
transmitting, then it would legitimately take 20-30 minutes.
Telrad BTS's are like that too. Pisses me off if I ever have to reset
the power.

Modern GPS receivers work surprisingly well, if not very accurately,
from inside a single floor wood framed house... My oneplus one will
pick up 6 satellites while standing in a central hallway 15'+ from
any window. Should be accurate enough to get a location within 75'.
All bets are off if it is a concrete framed apartment building or
something like that.
I still find it amazing that anything works at -162 RSL. Thanks to
tiny channel size and very basic modulation.

Canopy NAT seems to break it with regularity. It might also fail if
the GPS location that it reports is not within a 1/4 mile of where
the customer address is.
Also requires enough GPS (like near a window) to get a GPS lock.

Customer uses 10.x.x.x addresses internally, behind Cisco ASA
firewall (which I don't manage).

I do see some udp/500 and udp/4500 packets, I think that means
something is using UDP for IPSEC NAT traversal?
