<div dir="ltr">I have created an environment with the same config

video, I have changed (flip) the public/internal IP addresses on
rtpproxy and I can get half call leg working properly,
includding video.<br>
<br>
However, I am testing video calls. So I got another question on
top of the original post: Can we use rtpproxy also for video or
it only supports voice rtp proxy?<br>

<br>
Yes, it works for both audio and video at the same time. As an
example, see my ipv4-ipv6 tutorial where I used it in bridge mode
and tested with video using Jitsi:<br>

<br>
Hello,<br>
<br>
have you looked at sip trace and checked what are the IP
addresses in the SDP? Maybe you need to swap the flags i and
e.<br>
<br>
You can eventually provide here the incoming invite as well as
outgoing invite, saying what you would expect to be in the
outgoing one, so we can give further hints.<br>
<br>
Cheers,<br>
Daniel<br>

<div>Calls were correctly going to the desired
rtpproxy_manage options. </div>
<div>Now I’m not quite sure I’m using the correct ones.</div>
<div>I had to specify the PUBLIC_IP or PRIVATE_IP in the
rtpproxy_manage calls in order to have the correct IP
address in the C and O headers of the SIP INVITE.
Without that, the public IP would be sent as C and O
params to phones on the private subnet.</div>
<div>In fact not a single call direction would give
correct RTP streams.</div>
