[cisco-voip] Slightly OT: Ephemeral port range question

[Ed Leatherman]

Follow-up on this thread hopefully to save someone else some time hunting
around CCO, the ephemeral range for CCM 6.x didn't make it into the TCP/UDP
port list doc, but it is corrected in the release notes:
Ephemeral Port Range

The Cisco Unified Communications Manager 6.1 TCP and UDP Port Usage document
requires the following update:

The Ephemeral port range for the system is 32768 - 61000.
