<div>Turning off security would get the phones registered but if you regen all your certs at the same time you will strand your phones on an ITL that can't be updated. If you have CTLs signed by etokens you will probably be ok one you rerun the CTL client. </div>
<div><br>
</div>
<div>This is why you configure certificate notification and act on it. Do your CallManager cert in one maint window, make sure your phones all reset and update their ITLs. Then do tomcat and the rest.</div>

<div dir="ltr">brian - if you find yourself in this situation, how do you fix it ? turn off the security profile on the phone so it is no longer required to authentication and then update the phone certs and re-enable the security profile ?</div>

<div dir="ltr">Nothing really stops working besides certificate warnings in the browser. The phones don't check validity dates. Only issue with a secure cluster is the CAPF on the publisher expiring since it signed all of the LSCs on the phones. CallManager
service will care about those being expired and they won't be able to re-register if they are reset.
