Hello,
It's off-topic, but it was several times discussed here on the list.
It seems that the upcoming 18.17 and 20.2 asterisk version seems to properly support path headers. From the announcement:
* [ASTERISK-30100https://issues.asterisk.org/jira/browse/ASTERISK-30100] - res_pjsip: Path is ignored on INVITE to endpoint (Reported by Yury Kirsanov)
This bug has been many years open. have not tried it yet, but it looks promising.
Cheers,
Henning
