If you want to do more than just get headers from the INVITE, then you'll need to use an actual SIP Proxy like Kamailio.

It looks like if I call Getvar and pass PJSIP_HEADERS() I can get the entire SIP header for a channel.  I also read (on stackoverflow) that the PJSIP_HEADER function will only return the headers from the INVITE of the _inbound_ channel.

If that’s correct, how would I get the headers from the outbound channel (second leg of the bridged call) INVITE ?  Or will PJSIP_HEADERS() in fact return the header from either inbound out outbound legs?

    I am connecting to the ARI with subscribe all, so I can see channels
    being created.  I now want to extract a variety of header variables
    (at the moment the from and to tag).  I tried to read them from the
    ARI but Asterisk refuses since the channel is not in a  stasis app.

    Is there a way to read these from either the ARI or AMI ?  I’m
    trying not to modify the dialplan.

ARI, No.

AMI, Yes[1].
