I inherited a single SPA509G from a customer, trying to use it with Asterisk. SW Ver. 7.4.8.a, HW Ver. 1.0.3
I can access the web interface, but when I click "Admin Login" I get only a page "403 Forbidden!".
I've tried factory reset via the phone's menu, disabled/enabled web access, disabled DHCP and used static IP address. Set Transport Protocol to "tftp" and tried upgrading firmware (7.5.2b) from a Windows PC.
No success with either - still can't get past the "/admin" URL.
Any suggestion are greatly appreciated.
Thanks,
Thomas
