[asterisk-users] PJSIP_HEADER - Diversion header manipulation

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

Davor,

Have you attempted to do a Set(PJSIP_HEADER(remove,Diversion)=)) in your
add_diversion context to remove the header Asterisk is passing through?

[asterisk-users] PJSIP_HEADER - Diversion header manipulation

Hi John,

yes I tried to do "remove" and "update" of the Diversion
header but I
get "No headers had been previously added to this session" error. As
you
can see from the configuration and logs below I can successfully add 
another From: header and make update to that additional From header.

I previously missed to notice change in the domain part of SIP URI in 
Diversion header. Phone sets Diversion header to "836 at 10.201.1.19"
and
Asterisk makes change in domain part of Diversion hdr in INVITE message 
to "192.168.1.101". This server has two network interfaces and 
192.168.1.101 is set on eth0. So, Asterisk makes a change to Diversion 
header but not the one set by PJSIP_HEADER function.

Davor

The Diversion header is created and managed by the implementation in PJSIP
itself. It can't be edited using the PJSIP_HEADER dialplan function, but can
be manipulated using the normal core mechanisms[1].
