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