It looks like the carrier is only sending you the last 3 digits of the
called DID.

Once mod_freetdm figures out what the called number is it will try to route
it in whatever context is specified in your freetdm.conf.xml file. In your
case it goes to default as you can see by this log line:

2013-08-13 11:08:45.145709 [INFO] mod_dialplan_xml.c:558 Processing
<7502029000>->000 in context default

See my answer to question #2. Basically you need an extension with a
condition that matches 000, something like:
<condition field="destination_number" expression="^000$>
