I asked anybody whether there is a way how to achieve my goal.
Somebody that is more skilled than I am.<br>
I was asking if there are "trivially easy ways to accomplish my
goal". Freeswitch is an awesome software, I like it very much, but
replacing kamailio with freeswitch is not a solution for me (in our
environment).<br>

Its all software, anything is possible with enough code
modification. We don't have a setting to do those things right
now, as it doesn't make any sense when there are trivially easy
ways to accomplish the same goal without writing any more code.

Michael, <br class="">
I understand, so isn't it possible to have SDP with
m=audio lines SAVPF, SAVP and AVP all together ?<br
class="">
Because I set media_webrtc=true, AVP and SAVP lines are
replaced with SAVPF.<br class="">
If I had all three m=audio proto lines I was able to
manage it with Kamailio.<br class="">
<br class="">
And back to my first question, is that possible to set
different ports for m=audio lines in SDP ?<br class="">

If you don't use some other engine to handle webrtc,
then if you are calling something that is registered
to you over websockets it will automatically enable
media_webrtc for you. Otherwise you'll need some
external way of knowing if the endpoint is webrtc or
not so you can apply the settings properly.

Hello, <br class="">
<br class="">
My freeswitch's INVITE sdp offers two
m=audio lines. (RTP/SAVP and RTP/AVP). <br
class="">
That's OK, because I want it so ;)<br
class="">
<br class="">
But both use the same audio port number. <br
class="">
Is that possible to change this behavior ?
To use different audio port numbers for each
m=audio line ...<br class="">
Please check my example below. In SDP from
my freeswitch, both m-lines have <b
class="">m=audio </b><b class="">22284</b>.<br
class="">
<br class="">
The reason, why I want to change this is
WebRTC and RTPengine. RTPengine changes this
INVITEs to RTP/SAVPF.<br class="">
And the changed RTP/SAVPF is then not
acceptable for chrome browsers. Firefox
works well (so far).<br class="">
I already reported this to the RTPengine but
they say the problem is with INVITE from
freeswitch because the m-audio lines use the
same port.<br class="">
<br class="">
My example :<br class="">
incoming calls -> Media Server
(freeswitch) -> Kamailio (sip and
websocket proxy) -> WebRTP and SIP
clients <br class="">
<br class="">
I have found a feature <b class="">media_webrtc=true</b>
so I could avoid using rtpengine for webrtc
clients (that would be really awesome), but
then classic sip clients are offered only
with RTP/SAVPF and most sip phones do not
know RTP/SAVPF so the calls are rejected :(<br
