[Asterisk-Users] 403 forbidden error

[Ken Panco]

Please help,
    anyone out there have a fix for the 403 forbidden error...i am 
running asterisk with AMP but cannot get my budget tone 100 phones to 
register with my sip server....  i think the problem lies with the fact 
that the sip_additional.conf creates the call plan [ext-local] and not 
[from-sip]..I am a newbie to unix as well as sql administration and dont 
know how to manually add the [from-sip] dial plan to the amp 
database.... it could be a multitude of problems and what I think is the 
problem might not be causing it..i am really lost and have searched for 
fixes to my problem online and saw people with the same problem but what 
they did to fix it is not helping me..i keep getting the same 
error...please help....have been stuck on this problem for several days 
and dont know what to do now other than to just run asterisk without  
the nice amp web interface....the problem is probably a quick and easy 
fix for any one of you out there but I cannot seem to get it working 
seamlessly....PLEASE HELP

Thanks in advance,

Ken
