[Freeswitch-users] How Bridge users from one node of FS to conference in other node.

Hi, I try to create FreeSWITCH HA Clustering. I have node A and node B with ODBC and ESL client. Node A have conference. At Node B calling users which should be connected to conference on node A. As I read here : http://lists.freeswitch.org/pipermail/freeswitch-users/2011-January/067384.h... just bridge a user to conference. But how? If I use command like uuid_bridge <caller_uuid> <conference_uuid> I just disconnected. How Node B can know about conference on node A? As I understand FS do not store this information to table that create by ODBC?
