Hi Jack, I have tried out your suggestion but still no luck. I have cross check with the post attempt (FS console) and the domain/user info is correct. The return in FS console: 2011-09-19 13:21:57.001319 [CONSOLE] mod_xml_curl.c:313 XML response is in /tmp/c0a9e205-c738-45bf-aaa2-50a6ac0168f4.tmp.xml 2011-09-19 13:21:57.001319 [WARNING] sofia_reg.c:1199 SIP auth failure (REGISTER) on sofia profile 'external' for [+6597293279@10.1.1.47] from ip 111.65.28.60 send 554 bytes to udp/[111.65.28.60]:33913 at 05:21:57.005661: ------------------------------------------------------------------------ SIP/2.0 403 Forbidden Via: SIP/2.0/UDP 10.223.215.249:5060;rport=33913;branch=z9hG4bKPj0LZUqL1S3xjOHQ5mFNQDWrf5TSZZUWER;received=111.65.28.60 ..... my XML return is like in image http://freeswitch-users.2379917.n2.nabble.com/file/n6807266/mod_xml_curl_content.jpg Do you have any other idea of what might be the problem?
