[OpenSIPS-Users] Getting header from 302

Tue Jun 1 15:19:45 EST 2021

Yes, I see it is documented.

So the reply header is only availanble on the "onreply" route, not on the
"failure" route. That was my problem. I do indeed use an avp to store the
header.
I ended up getting the header on the "onreply" and storing it in an avp,
set a flag and then drop(). I noticed the "failure" route is then executed.
>From there I can send the processing to the invite route and by  checking
the flag, adding the header from the avp.

Thanks for your help!
