We had phones in Perth hooked up to an Asterisk box in Melbourne, and

How far (physically) is the Asterisk server location from the
location of the phones? Have you tried pinging the Asterisk server
from the network to which the phones are connected?
As a rule of thumb, If the two sites are within 2500 miles of each
other and the network connection between them is working properly,
the round trip time for a 64 byte ping should be less than 100 ms,
the round trip time should not vary from one ping to another by more
than 2-5 ms (typical), and there should be virtually no dropped
packets (well under 0.1%).
If your network does not meet these standards, then it may well be
the cause of your problems. In that case, if you e-mail me a
traceroute from the phone location to the Asterisk location as well
as the output of a ping from the phone location to the Asterisk
location (preferably including at least 100 repetitions), I will
take a look at it and let you know what I think.
I have phones in the US conencted to and Asterisk box in .AU, the ping
time averages 230ms, (ADSL at both ends) and the call quality is just fine.
The problem will be if packets are being dropped, of if one or other of
the end-points is getting saturated. I have Linux/IPTables with ToS and
QoS giving voice data the highest priority.
