Testing Questions - P-Asserted-Identity headers

Howdy folks!

So, I’m working with a company that’s asked me to send them packet traces of my phone calls, and after the first round of them was told that my packets did not contain ‘P-Asserted-Identity’ information in the SIP headers.

First off, why do I need or want this? Seems like an extra step, quite honestly, as I can fill those headers with as much arbitrary data as I see fit. Having a dickens of a time getting these packet traces right, so I figured I’d come here and see if anyone else has felt the same pain.

Feel free to ask questions about my setup and what’s going on, and I’ll happily form things up and post them (of course, stripping out anything proprietary, confidential, etc.)
