One voice VLAN for campus?

Our phone vendor is suggesting that we transition to a single voice VLAN for the campus. "Campus" means two buildings, connected underground. All devices connect to one of five Cisco 3750 switch stacks, and all stacks are connected via 10 Gb fiber with L2 and L3 on most of the links (one link is L3 only, but we can reconfigure it). Do you think it's ok to trunk a single VLAN throughout to serve all voice? Total number of phones is 100 now, going to 150 when we remove the digital devices and move to all IP.
