Thanks for the suggestions so far! I am using digest authentication. I have not tried restarting Tomcat, but since I did not upload anything to CallManager, I'm not sure it'll be required. Either way, easy enough to try it!
I know with a SIPS trunk, I was required to upload a client cert into CM-trust. I guess I was just hopeful that I wouldn't have to do it with client devices because I can't get my hands on the software to test myself, so I have to work through someone else. Hmm, maybe I'll consider VPN if I can't get it working otherwise.

So, from that much your assessment that the softphone needs to be presenting some sort of client certificate sounds about right. I would be curious to hear what the outcome is, as we're starting to let in some more 3rd party devices from Axis, ClearOne, Crestron. 9/10 times I ask about SRTP and SIPS support and the customer has no idea what I'm talking about, but some day someone is going to call my bluff. I'm not sure what your application is but a targeted VPN connection is probably going to be an easier lift, especially if you're going to enable TLS 1.0.

Seems that is the thing with Cisco these days..... and I am told that in newer versions, restarting the server will be required, as restarting the service isn't enough.... Only thing I though of was ok windows....

I have it working with Cisco phones and Jabber, but am trying to get a third party client working. I'm on CUCM 12.0. So far, I'm running into an issue with the TLS handshake. The client is using TLS 1.0, and I confirmed that my CUCM nodes do support 1.0. I've put the CallManager cert in the trusted root (local machine) on the Windows client. When attempting to register the client, CUCM gives an error "peer did not return a certificate." That led me to think that I would need to get a signed cert uploaded as a CM-trust cert. I opened a ticket with TAC to ask if that's the case (would rather not have to do a client cert if I don't need to) and they suggested I may not need one. I haven't been able to get more out of them on this yet (after a week), so I figured I'd ask here.
