[Freeswitch-users] FIFO from public context

Hi all, I am trying to use FIFO and followed the simple call center example here: http://wiki.freeswitch.org/wiki/Simple_call_center_using_mod_fifo When the dialplan is in default context and the call is made from a registered client, it works fine. However, if I move the dialplan to public context and make the call through sip call on another FS server or let my services provider forward the call my the sip address, FIFO will not work and no agent is ringed. Checked the log, it says "INCOMPATIBLE_DESTINATION" when trying to call agent. Can anyone help? Thanks.
