Also it is even possible to add SDP attribute by
adding new data_lump?
Isn't data_lumps dedicated to manage SIP message headers?
Lumps work also for message bodies.
Have a look at modules/nathelper/nathelper.c -> fix_nated_sdp_f()
There is example of insert_new_lump_after() where stuff is added to body.
I have not personally written code that adds lumps to messages, but removing
from body works perfectly with data lumps i.e. sdpops/sdp_remove_line_by_prefix().
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?"
In core there seem to be only SDP attribute get functions (/parser/sdp).
Examples of body modification can be found from different modules
(sdpops, nathelper, rtpengine, mangler).
If it is not implemented yet how can I contribute? It
is easy as modifying
`buf` of `sip_msg`?
I think core committers can comment more on this, but in my view contributions
to sdpops -module would be great. For script writer or C module functions.
