[Freeswitch-users] Detect source IP of a call

[Steven Ayre]

You can set a cidr="" attribute on a user in the user directory, the calls
from IPs matching that cidr will then authenticate as that user (by IP
instead of by password). You then have the ability in the user directory to
set variables which will be set when the call comes in from that address.

You can use mod_xml_curl to generate the user directory dynamically, which
allows you to integrate it with a database if you wished.
