This is correct. There is nothing in Asterisk or the channel drivers to
allow this. You would need to define a mechanism to do so and implement
it in the code.

Hello,

As far as I know there is no way to read or write the INVITE's body, 
neither with chan_sip nor chan_pjsip.

Hello,

I'm having a look at section 13.1 from SIP Connect v2 doc (see [1]).
It refers to RFC6442 which gives the following example (sorry for its 
length):


INVITE sips:b...@biloxi.example.com 
 SIP/2.0
   Via: SIPS/2.0/TLS pc33.atlanta.example.com 
;branch=z9hG4bK74bf9

   Max-Forwards: 70
   To: Bob >
   From: Alice >;tag=9fxced76sl
   Call-ID: 3848276298220188...@atlanta.example.com 

   Geolocation: >

   Geolocation-Routing: no
   Accept: application/sdp, application/pidf+xml
   CSeq: 31862 INVITE
   Contact: >

   Content-Type: multipart/mixed; boundary=boundary1
   Content-Length: ...

   --boundary1

   Content-Type: application/sdp

   ...Session Description Protocol (SDP) goes here

   --boundary1

   Content-Type: application/pidf+xml
   Content-ID: >

   
   http://www.opengis.net/gml;
  xmlns:dm="urn:ietf:params:xml:ns:pidf:data-model"
  entity="pres:al...@atlanta.example.com 
">

    
  
    
  
    
  32.86726 -97.16054
    
 
    
    
  false

   --boundary1--


1. Adding or reading the lines bellow seems easy. How can you add a 
whole application/pidf+xml section as above either using SIP or PJSIP ?
   Geolocation: >

   Geolocation-Routing: no

2. Reciprocally, how can you read such application/pidf+xml section an 
incoming call ?


3. What do you know of this RFC 6442 adoption within SIP industry ?

Best regards
