Asterisk as MOH server only

Hi all,

I do have asterisk running (ATCOM IP08) in my network (it is a requirement this device to be in the network). But ATCOM IP08 is with limited system resources and it cannot handle advanced features like Music-on-hold and voicemail. I am thinking to bring-up another asterisk server on the same local network, dedicate this to be a voicemail and MOH server only, this will offload the task to the new server from ATCOM IP08

How complicated this can be…? I never tried this. your inputs please.! if someone can put a summary on configuration side that would be great.
