It is probably filtering connections to port 110 of the exchange
server. I would assume that when the phone goes online it has a ip
address that is just part of a subnet that is allowed to connect
to the exchange server though the firewall. Either that or when the
phone goes online it is being routed though a machine that exists
behind the firewall.
Most likely its the latter of the two. I'm sure that if you could
snag the phone's ip address it could be DoS with attacks such as
land, jolt, nestea, ping of death, and those types of attacks so
they would want to have the phones protected behind a firewall.
