CCNP voice virtual home lab

Hi guys,
I'm building a home Vmware/GNS3 lab. I'm considering the CCNP voice track.
I read that CIPT2 includes multi-site distributed call processing. I managed to install a publisher and a subscriber as a cluster on vmware. I'm watching Blindhog's videos about building a GNS3 voice lab (with PSTN emulating router)
Do you think I need additional clusters per each site? or is it enough to have CUCM server on HQ and one CUCME per branch?
