[Freeswitch-users] call to the phone registering with xml_curl failed

Hi, I have two phone (x-lite), one (ext 1018) registering with xml_curl and the other (ext 1001) registering locally. I was able to make call from ext 1018 to ext 1001. But the call from ext 1001 to ext 1018 failed. I cut and pasted the console log in http://pastebin.freeswitch.org/13044. Any clue? Thanks, e
