<p class="MsoNormal">I’m trying to use the phone proxy feature on a ASA 5520 running 8.4(3). We are running CUCM 7.1.3 and I’m trying this with a 7941 phone. A colleague of mine who is no longer here claims to have set this up successfully and I saw that
it was mostly configured with the exception of the CTL not being enabled. The documentation I’ve found on this isn’t great, but I followed this:
<a href="https://supportforums.cisco.com/docs/DOC-1364">https://supportforums.cisco.com/docs/DOC-1364</a>. It appears that the phone is downloading the phone config file, but it just sits “Registering” before it cycles and tries again. These are the status
messages that I see:<o:p></o:p></p>
<p class="MsoNormal">SEP001e4a0bcc00.cnf.xml<o:p></o:p></p>
<p class="MsoNormal">No CTL installed<o:p></o:p></p>
<p class="MsoNormal">File Not Found: CTLFile.tlv<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’ve enabled phone-proxy debugging and tls-proxy debugging and I don’t see anything indicating an issue. I’ve tried a CIPC phone and the result isn’t any different. I can successfully request a phone config file using a TFTP client on
a computer.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
