I've finally managed to capture one of the messages responsible for the issue, and it looks like the Identity header is malformed - it is missing the alg and ppt parameters. I'll try to mock up and replicate the behavior.

That was my first thought, but I didn't want to jump to conclusions here. It's a valid URL and I'm able to download the certificate. I believe that the signing certificates should be cached, but it could be the first attempt to grab this specific certificate. I just figured out how to get the core dumps on this system today, so it's the only example I have but I will be checking to see if it looks to be consistent to this cert/vendor.

I'd go to frame 8 and print the value of _secsipid_get_url_val.s / _secsipid_get_url_val.len. It's obviously not NULL, but I wonder what it's pointing to.

Back trace is here, so I think it's a secsipid related problem? Slightly sanitized this output (Removed SIP message specifics in step #42). What should be my next course of action?
