asterisk users - Nov 2006 - Why only one out of many IP Phones re-registering every one minute

On one of my servers I have many IP phones connected, locally and remotely,
and all of them have register expiry set for 1 min. But on Asterisk CLI I
see only one of them, extension 502, re-registering every single minute.
None of the others re-register or info doesn't come on the CLI screen. This
one phone is remotely connected. What is the reason for this. And also
everytime it re-register, the port on which it is registered is changed.

Now I know that this has something to do with the NAT for sure. But why and
how, I don't know. I changed DHCP settings on my router to expire lease time
in 1 hour. Then I could see on Asterisk CLI phones getting registered every
hour. Then I changed it back to 7 days. But still some phones kept on
re-registering every hour. The register expire setting on the phones
themselves doesn't causing this message to display on Asterisk CLI,
doesn't
matter how frequently they are re-registering on Asterisk. I wonder how is
this handled by the router or NAT device.
