Yes, its a feature, i know. I was just looking at how this feature was
tested, as mentioned in its logs,

2010-01-04 15:01:51.945020 [INFO] mod_dialplan_xml.c:408 Processing
21653XXXXX->121637XXXXX in context termination
2010-01-04 15:01:52.054466 [ERR] mod_xml_curl.c:310 Received HTTP error 0
trying to fetch http://192.168.0.2/gateway.php
2010-01-04 15:01:52.054545 [CONSOLE] mod_xml_curl.c:317 XML response is in
/tmp/6632ebb1-d19f-4d51-a07e-ec2ce0387f83.tmp.xml

Thank you.
