[cisco-voip] CUCM Location question

[Erick Bergquist]

Ah, thanks. We're going to do proactive method. Whats the latest 5.1.3
ES you would go with?  I did some bug hunting yesterday and found a
bug involving cdcc leaks that was fixed in 5.1.3 2107 but didn't jot
down the id. It looks like 2104 is the latest on the download page.
