Hi,
It should work as long manager credentials and manager_host remain the same no matter the server/role. The only thing you will lose on a remotely FOP2 server is access to recordings, unless you configure some kind of shared volume for them (outside the scope of fop2 itself). If you do not use voicemail explorer or access to recrodings, then you won't miss anything in particular, queue functions will work the same as on a local server instal.
Best regards,
