Hello, when I try and register an extension I get the following errors, can someone let me know what this means?

 2(4712) ERROR: <script>: request: REGISTER from sip:1001@my-nated-IP:5060 to sip:my-nated-IP:5060

 2(4712) ERROR: <script>: request: SUBSCRIBE from sip:1002@my-nated-IP:5060 to sip:1002@my-nated-IP:5060

4(4714) ERROR: <script>: request: PUBLISH from sip:1003@my-nated-IP to sip:1003@my-nated-IP

Thank you,

Arun
