Yes, it is Supported, but note that Cisco Unified Communications Manager 5.0 and later require or recommend (depending on server model and software release) minimum memory and disk size as described in the table below. For Cisco Unified Communications Manager 8.0(3) and above, it is strongly recommended to upgrade to minimum 4GB RAM and 146GB disk drive; whether this is necessary for your deployment is design-dependent and depends on call volume, installed locales, dial plans, phone firmware loads, music files, etc. Use
