I don't understand the story about 0000-remove-third-party.patch. Could
you explain ? All patches are provided by Asterisk, they are at
https://github.com/asterisk/asterisk/tree/16.0/third-party/pjproject/patches.

One issue with this is that 16.0 is a branch name, so the patches that
you download are not guaranteed to be stable over time.

Also, what is the upstream status of those patches ? Is Asterisk
actively contributing those patches to upstream pjsip, or are they
doing de-facto a fork of it ?

Thanks,

Thomas
