I'm  trying to use mod_fifo where Freeswitch will dialout to reach "agent". but bump with some odd behaviour. Below are scenario that demostrate this different behaviour  : 

ext.5001   -> FS send invite to each destination one by one sequentially 
ext.5002   -> FS send invite to all destination simultaneously 

I'm looking to use dynamic fifo method as on ext.5002, but wanted FS to do invite sequentially as on ext.5001. 
Is there anything i should do on 5002?
