[asterisk-users] How to read or write Geolocation (RFC6442) data in SIP/PJSIP messages ?
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:bob at biloxi.example.com SIP/2.0
Via: SIPS/2.0/TLS pc33.atlanta.example.com;branch=z9hG4bK74bf9
Max-Forwards: 70
To: Bob <sips:bob at biloxi.example.com>
From: Alice <sips:alice at atlanta.example.com>;tag=9fxced76sl
Call-ID: 3848276298220188511 at atlanta.example.com
Geolocation: <cid:target123 at atlanta.example.com>
Geolocation-Routing: no
Accept: application/sdp, application/pidf+xml
CSeq: 31862 INVITE
Contact: <sips:alice at atlanta.example.com>
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: <target123 at atlanta.example.com>
<?xml version="1.0" encoding="UTF-8"?>
<presence
xmlns="urn:ietf:params:xml:ns:pidf"

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 at 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

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.

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. -- Joshua Colp Digium, Inc. | Senior Software Developer 445 Jan Davis Drive NW - Huntsville, AL 35806 - US Check us out at: www.digium.com & www.asterisk.org
