[cisco-voip] What controls how quickly MWI is resynced?

[Robert Kulagowski]

In a 72 port Unity 4.2(1) system, how come going to UTIM and performing 
a "Resync Now" doesn't use all 72 ports?  All the ports are available 
for MWI, but from watching the PortStatusMonitor it's only using Port 72 
for the most part, and port 70 and 71 infrequently, so the resync (after 
a failover to the secondary) seems to be taking a very long time. (At 17 
minutes and still counting according to the eventvwr.)
