Hi there,

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.

Nitesh,

You need a B2BUA function <https://www.tutorialspoint.com/session_initiation_protocol/session_initiation_protocol_b2bua.htm> with the help of a topo-hiding module with opensips as Bela shared in his email. Also, install the RTP proxy on the same opensips box (not necessary if you need separate signaling and media boxes).

Far end party will not be able to see the A-party information.

I hope this will help.

    Hi Nitesh,

     1. Check the topology hiding function:
        https://opensips.org/docs/modules/3.2.x/topology_hiding.html
        <https://opensips.org/docs/modules/3.2.x/topology_hiding.html>
     2. Use e.g. rtpproxy:

    https://opensips.org/docs/modules/3.2.x/rtpproxy.html#func_rtpproxy_offer
    <https://opensips.org/docs/modules/3.2.x/rtpproxy.html#func_rtpproxy_offer>

    I hope these help!

    *Subject: *[OpenSIPS-Users] - INVITE (SDP) includes Originators IP
    info

    Hello All,

    This is my first OpenSIPS project so I'm a newbie!

    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:

    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.

    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.

    Any insights will be highly appreciated.

    Cheers,

    Nitesh
