[asterisk-users] Is it possible to perform PJSIP Add Header prior to calling Queue and have it part of the INVITE packet?

[Dan Cropp]

I have both the PJSIP add and the chan_sip way of adding SIP headers in there.  The Verbose is showing the variable value is there.
The INVITE to PJSIP/Agent1 does not include either X-My-DNID or X-My-DNID2 headers.

exten => 1234,1,Verbose(X-My-DNID:${MY_DNID})
same => n,Set(X-My-DNID=${MY_DNID})
same => n,Set(PJSIP_HEADER(add,X-My-DNID2)=${MY_DNID})
same => n,Dial(PJSIP/Agent1)

Are you using this method of setting headers on PJSIP?

I was able to get the basic concept to run.
However, it seems PJSIP INVITE for the Dial also does not support added headers.

The Local channel dial plan did have the channel variable values.  I added them as SIP headers, then Dial(PJSIP/Agent).
The INVITE for the Dial on PJSIP continues to not include the SIP Headers I added.

For chan_sip, I have no problem with this.  Even the original Queue code I had includes the added SIP headers with it’s INVITE to the Agent.

Local channels: http://www.asteriskdocs.org/en/3rd_Edition/asterisk-book-html-chunk/DeeperDialplan_id324598.html

This explains adding members to queues, although it doesn't specifically provide an example of using local channels in a queue: http://www.asteriskdocs.org/en/3rd_Edition/asterisk-book-html-chunk/ACD_id289508.html

Basically, read that book, and if you get stuck ask for help.

I’m taking over for someone else’s code, so I must admit I’m still learning the Agent and Queue concepts.  Local channels are something I have not used either.  Would local channels essentially be an internal bridge?

How would I
“Register Local/number at agent in the queue on behalf of the agent (replace number with the agent's extension number)”

To add a header to the call leg that goes to the agent, try using a local channel to activate dialplan on the outbound call:

Register Local/number at agent in the queue on behalf of the agent (replace number with the agent's extension number)

In dialplan [agent], wild card match the number, add the header, and then Dial(PJSIP/{$EXTEN}) to send the call to the agent.

I have a call coming in.
I need to add a SIP Header to the channel.
Then, I need to send the call to the Queue so it is sent to the Agent.

The SIP header I added, I need to have appear in the INVITE sent to the Agent.

It works in chan_sip.  I send the call to a macro which does…
n,SIPAddHeader(My-Header-Name:${MY-HEADER-VALUE})
n,Queue(${ARG2})


In PJSIP , this doesn’t seem to work.  Is there any way to add custom PJSIP headers to be sent as part of the INVITE to the Agent?
When I look at the code, it seems as though the INVITE doesn’t look for any custom headers to be included with the INVITE packet.  Is this correct?

Have a great day!
