ENUM

This is really pretty easy to set up.

Fix enum.conf.xml

vim /usr/local/freeswitch/conf/autoload_configs/enum.conf.xml

Find:

<route service="E2U+SIP" regex="sip:(.*)" replace="sofia/${use_profile}/$1"/>

Change it to:

<route service="E2U+SIP" regex="sip:(.*)" replace="sofia/internal/$1"/>

Enum Dialplan

Make sure to change YOUR_AREA_CODE

vim /usr/local/freeswitch/conf/dialplan/default/00000_enum.xml
