[asterisk-bugs] [JIRA] (ASTERISK-26178) Setting custom SIP headers in PJSIP when using ARI

[Sotiris Ganouris (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-26178?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=238953#comment-238953 ] 

Sotiris Ganouris commented on ASTERISK-26178:
---------------------------------------------

Hey, Joshua, thanks for the reply. 
That means that when doing a request to originateWithId: POST /channels/channelId

I can pass at the body of request a json like so:
{quote}
{"variables":{ "PJSIP_HEADER(add,P-Asserted-Id)": "1234567890 <sip:1234567890 at x.x.x.x>" }}
{quote}

Is that the correct syntax for using this dialplan function when originating a channel?

> We currently have an application that is using the ARI exclusively for managing calls. What we need is a mechanism to set custom SIP headers when originating a new channel via the ARI. This is possible with the old chan_sip driver but creating a variable called "SIPADDHEADERXX", the contents of which are added to the INVITE as a custom header when the INVITE is created.
> We need the same functionality for the PJSIP channel driver so I have created a patch for chan_pjsip.c that implements this functionality in the same manner - you can set a varaiable called "PJSIPADDHEADERXX" and in the call() method in chan_pjsip.c it will add the header to the INVITE before sending it.
> This is working for me right now, I would just like to know though whether this is something that has been otherwise planned already? I can't find any reference to it here or on Google. If not, is this a valid/recommended means of doing this?
> I'm happy to do the work in order to implement this properly, if someone could give me some guidance as to how best to implement it? I'm sure someone else out there also needs this functionality.
> I've attached the patch here, it works great in versions 13.5.0 and 13.9.1 where I have tested it thus far.
