[cisco-voip] ITL and TVS question - CUCM 8.5.1.14048-1 and Secure URLs not working (corp dir, etc)

[Ted Nugent]

Wow... this is the 3rd time I've seen this issue in less than a week.... A
buddy of mine just hit this yesterday and I hit something similar last week
after a client enabled DNS on their cluster. They worked directly with TAC
and did not find a resolution in a "timely manner" so they called me. We
walked through everything in the link below as well as what TAC recommended
and the only thing that fixed the problem was blowing away the ITL on the
phone. That of course was not an acceptable answer so I sent them back to
TAC to see if they could find more info.... long story short they had to
delete the ITL on all their phones to get resolution.... Needless to the
say the client was furious and understandably so... I understand the why
and the how but can't see how crushing the ITL on EVERY phone is an
acceptable workaround for such a minor "whoops"...
Sadly with the changes in the TVS I see a ton of this in our future because
clients do shit without understanding the consequences and this is a
serious consequence for such a MINOR change....
 Yes i know we can go BUY a utility to assist with deleting the ITL but if
that is the answer then you've missed the point.
