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
<mailto:sips%3a...@biloxi.example.com> SIP/2.0

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: <cid:target123@atlanta.example.com
<mailto:cid%3atarget...@atlanta.example.com>>
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
