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

[Ed Leatherman]

Probably a dumb question...

I'm a little confused about the "official" ephemeral port range and cisco
callmanager/related products. i've always ran across at least two different
definitions of this port range, example from wikipedia:

BSD <http://en.wikipedia.org/wiki/Berkeley_Software_Distribution> used ports
1024 through 4999 as ephemeral ports, though it is often desirable to
increase this allocation.
The IANA <http://en.wikipedia.org/wiki/Internet_Assigned_Numbers_Authority>suggests
49152 to 65535 as "dynamic and/or private ports".

The ncFTP page that it lists as a source is even less specific and has
different ranges for different OS platforms.

Does callmanager use the IANA version, or some larger range for example for
H.245, TFTP, etc?
The port usage document that I have on ccm 4.1 just lists "ephemeral" for
the ports on some of these protocols, and it even has ephemeral in its
glossary but doesn't define what range its using.
