Probably a dumb question...<br><br>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:
<br>
<p><a href="http://en.wikipedia.org/wiki/Berkeley_Software_Distribution" title="Berkeley Software Distribution">BSD</a> used ports 1024 through 4999 as ephemeral ports, though it is often desirable to increase this allocation.
<br>The <a href="http://en.wikipedia.org/wiki/Internet_Assigned_Numbers_Authority" title="Internet Assigned Numbers Authority">IANA</a> suggests 49152 to 65535 as "dynamic and/or private ports".</p><p>The ncFTP page that it lists as a source is even less specific and has different ranges for different OS platforms.
<br></p><p>Does callmanager use the IANA version, or some larger range for example for H.245, TFTP, etc?</p>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.
