Thank you, Mikko,
I need to perform this actions inside my module (I don't want to use config
files and config functions to perform this actions) because the module
performs more actions than that ;-)
Also this means that it is not possible for me to just work on top of the
sdpops.
But thanks I will look at data lumps. It's shame that all useful functions
such as `msg_apply_changes()` (
https://github.com/kamailio/kamailio/blob/fcdf5f9cfff634ebfa736d7084d5e5483…)
are static so it means that I need to copy&paste them when I want to use
them within module.
Also it is even possible to add SDP attribute by adding new data_lump?
Isn't data_lumps dedicated to manage SIP message headers?
I just need a solid answer for question: "Is the adding attribute to SDP
body implemented in Kamailio? If yes where can I find it and how can I use
it?"
If it is not implemented yet how can I contribute? It is easy as modifying
`buf` of `sip_msg`?
I am sorry maybe the subject of this email is not clear enough. I mentioned
changing SIP message but not SDP body.

I have function where I cast `sip_msg`'s
`body` to `sdp_info` structure
and
within this function I am changing some fields in
`sessions` and
`streams`
list.
I am able to see changes when I am printing them after message leaves the
function but Kamailio sends the original message not the changed one. Do
I
need somehow let the Kamailio know that the
message was changed and it
should rebuild `buf` field? Or I need to change directly `buf` field
within
`sip_msg`?
You need to handle message modifications as data lumps.
Have a look at Kamailio development guide:
http://www.asipto.com/pub/kamailio-devel-guide/#c14datalump
Also, look if you can extend sdpops module instead of baking new one:
http://kamailio.org/docs/modules/devel/modules/sdpops.html
Hope this helps :)
