<br>
Actually you do not need the B2B, you can achieve the same kind of
privacy (at SIP level) with dialog module and topology_hiding
module together.<br>

<div>You need a <a href="https://www.tutorialspoint.com/session_initiation_protocol/session_initiation_protocol_b2bua.htm" target="_blank">B2BUA function</a> with the help of a
topo-hiding module with opensips as Bela shared in his email.</div>
<div>Also, install the RTP proxy on the same opensips box (not

<p class="MsoNormal">Hello All, </p>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">This is my first OpenSIPS
project so I'm a newbie! </p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">After going back and forth with
"uac_replace_from()", I was successfully able to
make a call from my ATA -> OpenSIPS ->
Outbound Provider -> CellPhone. All worked fine
with two-way audio except few issues: </p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">1) Outbound Provider was able
to see my ATA (Originator's IP/User-Agent/etc) in
SIP INVITE (SDP) which kinda raised some eyebrows
with Outbound provider. How can I block or strip
all the Originator's contact info in SIP INVITE
(SDP) and only send OpenSIPS info? Meaning I want
to protect my Originators and don't want to show
anything to the Outbound Provider. Outbound
providers should only communicate to the OpenSIPS
server. </p>
</div>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">2) When the call was up I
failed to capture any media/RTP on the OpenSIPS
server. I want to involve OpenSIPS in media/RTP
between ATA and outbound providers. How can I
force media/RTP to pass-thru OpenSIPS IP so I'm
not exposing Originator's IP.</p>
</div>
<div>
<p class="MsoNormal"> </p>

<div>
<p class="MsoNormal">Any insights will be highly
appreciated. </p>
