That's exactly right. Media flows around Kamailio, negotiated directly by the
endpoints in their SDP, to which Kamailio is entirely agnostic.

Thanks for your quick reply. So, Kamailio does nothing
with RTP/RTCP
packets? I think I understand (now when I think about it) - Kamailio
only
handles SIP messages by which in nested SDP two endpoints negotiate the
stream where media will go through? So RTP/RTCP media stream flow
directly
between two UA endpoints and Kamailio has nothing to do with handling
of
these packets. Could you, please confirm my thoughts?
All right but what if for example we have special UA that sends to
Kamailio
specially modified packet (non standard SIP). In my extension of topoh
module I have sanity_checks disabled so will Kamailio check this packet
before my module and drops it or I can receive, modify and forward this
packet? I mean modify this packet to standard SIP packet and forward it
to
another UA. I am just asking theoretically because in the moment I cant
try
this.

Hi,
I'd like to develop module for Kamailio which will be working with
RTP/RTCP packets. Is there any way to capture and edit RTP packet in
module
of Kamailio for example in module extended from
*topoh*?
Kamailio in itself is a SIP server, often acting as a SIP proxy. The
SIP
protocol doesn't handle media, it facilitates
setup and management of
a
media session. Adding a module for handling media
in Kamailio doesn't
really make any sense.
We do have modules that talk to external media servers. Look into
those -
like rtpproxy. The Kamailio module itself does
not handle media, but
communicates with the other server that in fact manages media
relaying.
Before you modify software, you need to understand the architecture
:-)
/O
In topoh there are two events SREV_NET_DATA_IN and SREV_NET_DATA_OUT
but
I didn't be able to capture any RTP packets
by them.
Thanks in advance for any help or useful information.
