Getting hammered by scanners - If I change my default ports, is it just changing for example from 5060 to 5076 - by looking for every place it says 5060 to 5076 in the ITSP Profile A and ITSP Profile B menus?
Change the (Voice Services)SPx Service->X_UserAgentPort ports for each SPx to a number not in the 506x range. You should not use a port that is used by something else. How do you know? I followed this posting:
http://www.obitalk.com/forum/index.php?topic=4067.40 . If you can change the X_AccessList values instead, that will mean you don't have to change ports.
I did not change the X_KeepAliveServerPort ports from 5060.
Do I need to mess with my router too with port forwarding?
I didn't.

I think this should become part of the setup process.
