[Asterisk-Users] Configure Asterisk with Radius

[K Wong]

I'd installed Asterisk, the app_radius.so and Freeradius.  They all
startup ok, but what's next to configure Asterisk to use radius?  I
looked at the WIKI already but am still confused.  So what should I
set in the radius server and what do I need to set on the radius.conf,
extensions.conf, sip.conf or iax.conf file?

Btw, I have the following in radius.conf as by default

 Service       Host:Port               Key             Timeout Retries
auth            127.0.0.1:1645          secret 10      3
acct            127.0.0.1:1646          secret 10      3

where secret is the radius client password

Any help is greatly appreciated.
