[Freeswitch-users] How to use fs_path?

FreeSWITCH Version 1.0.head (git-f17e962 2011-04-19 03-05-32 -0400) I am tring to send call through a sip proxy like this: <action application="bridge" data="sofia/internal/5038443019@XXX.XXX.XXX.225:5060;fs_path=sip:XXX.XXX.XXX.230:5060"/> It does not work. Whenever I make call, it immediately send to voicemail. What is the correct way to use fs_path? Gary
