<div dir="ltr">Hmm, on bryant's issue with the ITL / CTL files - if the time was right on servers and most phones but not a few then it sounds like those couple phones weren't getting updated configuration file/etc probably for awhile if deleting the ITL and CTL resolved his issue. Did the phones upgrade firmware also once the ITL / CTL was deleted (or didn't notice?). - Check out the Security By Default in 8.x document for more background. <div>

If, it's only some phones having the problem…then we assume the that ntp with the cucm is accurate…the pub will be the master and the subs will get ntp from the pub.</div>
