<p><span style="color: rgb(31, 73, 125);">I think I figured it out, but am
not sure that I understand. Why should the proxy be requesting tftp files with
the Internet address of the phone client if it is "proxying" for it? I missed
the part where the ASA has to be in path with traffic to the Internet from the
CallManager. I thought a proxy would act on behalf of the phones and the
phones would show up on the LAN with the ASA's Inside interface address. I had
to add a host route on my CCM/TFTP server to get TFTP to work.</span></p>

<p>I am trying to get the ASA Phone Proxy feature up and
working with CCM 4.1.3, but I am getting the following tftp error messages when
the cnf.xml file is requested by the ASA for the phone:</p>
<p> </p>

<p> </p>
<p>The phone boots and loads fine when on the local LAN, but it
errors when the ASA requests the same file.</p>
<p> </p>
<p>Any ideas on what this means, do I need to turn on more
detailed traces?</p>
<p> </p>
<p>Thanks,</p>
