<div dir="ltr">That's what it looks like. Starting in CUCM version 8.6, we started resetting all registered phones on the cluster whenever a certificate used in the ITL changed. This was to prevent the ITL from changing too much at once before the phones go the update such as regenerating CallManager.pem and TVS.pem at the same time which will force you to have to delete the ITL on all phones unless the phones got the updated ITL after the first certificate was regenerated.<div><br></div><div>It sounds like this bug is due to that behavior but I'm not sure why it repeats every 7 minutes. I would expect it to only happen the single time when the certificate database is updated.</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Oct 9, 2014 at 1:52 PM, Jason Aarons (AM) <span dir="ltr"><<a href="mailto:jason.aarons@dimensiondata.com" target="_blank">jason.aarons@dimensiondata.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
