Restarting TFTP on all nodes ended up fixing the issue. I had to reset phones afterwards and they basically did a reset, downloaded the new ITL file, did another reset and then came back up.<br><br>All cluster nodes now have a TVS entry in the Trust List as viewed from the phone LCD where before the TFTP restart they did not.<br>

-TFTP downloads (ring tones, etc) and TFTP config changes<br>-'show itl' from CLI is showing verification is ok on all nodes<br><br>When I do a TFTP get and download the ITL file from CUCM and compare the Md5 with the phone things match. Show ITL on the CLI shows verification is ok. However, if I open the ITLSEPxxxxx.tlv file in notepad, I am not seeing all of my servers listed in the ITL file. However, when I do a 'show ITL' from the CLI, all the servers show up in there. It is almost like the TFTP server has old versions of the ITL file (based on switch-version times? etc) and was not updated as other subs went through the switch-version from 7.1 to 8.5.<br>
<br>On a hunch, I restarted the TFTP service on a sub that no phones actually use for TFTP. After restarting the TFTP service, if I download the ITLSEPxxxx.tlv file and do a MD5, the value changed from pre-TFTP service restart. Now when I open the file in notepad, I see all of my CUCMs listed in the ITL file. <br>
<br>My question is, can I just restart the TFTP service on the sub that my phones are actually using for TFTP? I am thinking the TFTP restart will cause the ITL to update (and include the other cluster nodes) but I am not sure whether the phones will then fail with ITL mismatch or whether the phones will update their ITL file and now include the other servers.<br>
<br>I am also thinking of implementing the rollback to PRE 8.0 service parameter, resetting the phones to clear the ITL and then restart the TFTP service.<br><br>Any thoughts on whether restarting the TFTP service on the node that phones are using for TFTP will just update the existing ITL the phones use with the other CM nodes or whether that will in effect create an entirely new ITL which would then require manually deleting the ITL files ?<br>
