[Freeswitch-users] Need a help with topology

Hi, Now I have only on FS server which works very very well. As I would try to migrate more user to FS server I am implementing opensips before FS for load_balancing and also registration. I will use opensips also for cdr (if it will work ok, like fs) and for enum. On FS I have now few groups which are using group pickup in that kind of things. Is it possible to connect FS boxes together so that it will be possible to do group call pickup and still call from other FS box or would would you suggest or how to deal with this issue? The same with CFWD and etc. thanks! Miha
