I restrict this hole but this is far from an ideal solution, IMHO

http://192.168.10.1/admin/voice/

tab -> System

option -> Restricted Access Domains: your.sipproxy.com

*this works only before you click "Apply All Changes" in web admin

For permanent apply of this settings you must change config file via telnet. Also I use tftp to copy files to PC and back to router.

./home/usb_disk/cfg/misc/config.xml

Ended up dumping UC320W for freepbx - endpoint manager is pretty ordinary but compared to the UC limitations I can live with it

UC320W and asterisk security vulnerabilities
