<tt>Ciao Daniele!<br>
you should open (for incoming traffic) at least all the possible
UDP ports used by RTPengine.<br>
You should find the min and max value in config.yml, under
rtpproxy section (maxport and minport).<br>
<br>
Cheers,<br>
<br>

<div>That was not the problem. Thanks to your advice I
realized my providers send the RTP flow from a different ip
I thought, and I guess the opened 5060 UDP port is not
enough.</div>

</div>
<div>Any advice about opening traffic from the provider I'm
interconnected with?</div>

<div>Hi,</div>
<div>I'm new to C5 CE, so sorry if my question is
too banal.</div>
<div>I installed C5 mr7.1.1 on a AWS t2.medium
instance. I followed step by step the tutorial <a href="https://www.sipwise.org/doc/mr7.1.1" target="_blank">https://www.sipwise.org/doc/mr7.1.1</a>
and I also set the advertised-ip.</div>
<div><br>
</div>
<div>I created a peer (outbound/inbound). The
scenario is simple: I have a DID bought from a
provider and I need to receive and make calls via
SipwiseC5.</div>
<div><br>
</div>
<div>I was able to create the outbound registration
to the provider, but in the provider side I see
the registration comes with the private ip of the
EC2 instance (i.e. 172.xx.xx.xx): so when I make a
call to my mobile phone for example I see the
phone ringing but when I pick up the call I don't
hear any audio. <br>
</div>
<div><br>
</div>
<div>The rtp.log shows:</div>
<div><br>
</div>
<div>] INFO:
[313535313739363530363535363736-52dacv20j9ei]:

</div>
<div><br>
</div>
<div>Where should I specify my public ip in order it
is used correctly also for RTP stream? I didn't
find hints in the guide.</div>
</div>
</div>
</div>

<p>The advertised-ip is supposed to take care of that. You
can confirm it by looking at the `interface=` line in
/etc/rtpengine/rtpengine.conf, it should look something
like this:</p>
<p>interface = ext/<a href="http://172.31.25.213" target="_blank">172.31.25.213</a>!198.51.100.23;int/<a href="http://127.0.0.1" target="_blank">127.0.0.1</a>;int/::1</p>
<p>In rtp.log you still see the internal private IP address
since this is what rtpengine uses to actually send and
receive packets.</p>
<p>You can further confirm it by setting rtpengine's log
level to 7 (debug) and then looking at the outgoing SDP
body after rewrite in rtp.log.</p>
<p>Cheers<br>
</p>
