[Freeswitch-users] ACLs through proxy

[Bill W]

Hey Metik,

Thanks for the reply, and the pointers for doing it with xml_curl.

I'll guess have to do that in the short term, but in my opinion, having 
auth-acl be able to work through a proxy is very important as it is a 
vital part of a comprehensive security feature set.  And it would be 
much simpler to implement from an end-user perspective than the 
alternative of doing it in xml_curl.

As a matter of fact, I'm considering offering a bounty for that feature. 
  What is the going rate for that kind of thing?

Is anyone out there interested in coding this feature? Or chipping in 
for the bounty?


Thanks,
Bill
