Hi all,
I’m trying to rewrite Diversion header when call forwarding is done on
the phone. The phone sends "302 Moved Temporarily" response and sets
Diversion header to a local number, but before Asterisk sends this call
towards TSP provider I need to change Diversion header to a full PSTN
number. I am using PJSIP_HEADER in a pre-dial handler (configuration is
below). On the same call I can add some other custom headers (logs are
below).
Is there any chance I can rewrite Diversion header in this scenario with
PJSIP_HEADER function? Asterisk version is 16.0.1 built from source on
Debian 9.
Thank you
Davor
