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.

<div>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.
