In doing a little research, it seems the Referred-By header could be added
after the pjsip_xfer_initiate.
This is the approach PJSIP did for some code as far back as PJSIP 1.6.
/*
* Create REFER request.
*/
status = pjsip_xfer_initiate(sub, dest, tdata);

I asked the question on asterisk-users but did not receive a response, so I am
sending the question here.
I am running Asterisk 13.5.0.
A call comes in, Asterisk answers it. After some actions, the call needs to be
Transferred (SIP REFER) to another number. The other switch is responsible
The answer to this is actually pretty simple: adding Referred-By in
outgoing SIP REFERs is simply not implemented in chan_pjsip's
chan_pjsip_transfer() function.
As far as the syntax required for the Transfer() application, that's
probably a case where that needs to be clarified in

That code gets you about 95% of the way there.
The biggest difference would be that the pjsip_msg_add_hdr() call may
need to be broken up based on whether the SIPREFERREDBYHDR channel
variable is set or not. To determine that, you can use the
pbx_builtin_getvar_helper() function call declared
Yep, that looks like what I would expect it to look like. The only thing
that immediately jumps out as unnecessary is the
if (ref_by_val !ast_strlen_zero(ref_by_val))
line. You can get rid of the initial NULL check because
ast_strlen_zero() does that for you.
If you wanted to submit
Thank you Mark for the tips.
Is the code below close to what you were thinking?
I ran some initial tests and it seems to be working. I can override the
default Referred-By value by setting the SIPREFERREDBYHDR variable.
