[OpenSIPS-Users] Callpickup scenario help

[Miha]

HI to all,

i need a little help regarding one scenaria (What would be the best way 
to implement this).

I am having opensips which is heandling registration and load balancing. 
Behind opensips I am having FS servers. What would be the best way to 
implement group call pickup. I need to know to which FS server send I 
call which will do call pickup. I must intercept only ringing phones. 
Call pickup future I have implemented on FS as would be also for PBX 
futures.

thanks!
