Have you checked:
a) the fail2ban logs
and
b) the firewall rules in place on the server immediately after the phones get
kicked off
just to be sure this is not being caused by fail2ban somehow?

What happens if you then add just one Digium phone?
Does it, and all the other brands, work as normal?
If yes, try adding one more, then one more - maybe you'll find one specific
phone which is causing this problem.
If adding just one phone causes the problem immediately, try adding a different
one instead (in case the first one you added is the one with the problem).

Can you run wireshark or similar on the router / firewall at this location, to
see what SIP traffic you get going back and forth to the server at the time the
problem occurs?
