Opensips1.7 with MediaProxy

LAVerPNZ
Hi. Please help.
We have:
1.One server consists of: CenOS6.5 + Opensips1.7 + MediaProxy2.5
2.One MGW: Cisco AS5350
3.UserID=telephone number and registration on OpenSips through MySQL
4.Call to PSTN pass through MGW with prefix 9999:
route[4] {      prefix("9999");
      rewritehostport("192.168.0.3:5060");
      if (!t_relay()) { sl_reply_error(); };
        exit;}

Now, such a scheme works:

(UAC       )---->sip----->Opensips 1.7--->SIP--->MGW Cisco
192.168.0.65               192.168.0.2                 192.168.0.3
RTP---------------------------
-------------------------------->MGW Cisco-------->PSTN

In this topology visible

It's not safe, it's necessary to build a new wiring diagram:
(UAC      )--->sip,RTP---->(Opensips--->rtp,SIP------>)----->MGW Cisco--->PSTN
85.85.85.85                    (85.85.85.2     192.168.0.2)     192.168.0.3

questions:
1. to hide the network topology from the users (can be used dialog module, function: topology_hiding?)
2. hide RTP traffic to MGW for Opensips-server (can be used MediaProxy or rtpproxy)?
Please, give examples opensips.cfg-file ?

Re: Opensips1.7 with MediaProxy

LAVerPNZ
can be used B2BUA mode?
users do not need to see the MGW!
To no avail. TCPdump shows no exchange between OPENSIPS and MGW(Cisco).
I installed Mdiaproxy and RTPproxy...............ineffectually
Please help with configuration.

Here is an example CFG-file that works now:
The message "183" prefix and visible IP gateway. And that could be a threat
of fraud.
Here: if you use the function topology_hiding (); it does not happen a fair
exchange:
"BYE" comes to the message "404", "Not here" rather than "200 OK"
I use client_nat_test to cut off all requests for registration are NAT, but
it does not work!

Hello,

The best options for you is to use dialog module with topology hiding. This can be easily combined with any of the media relays (rtpproxy or mediaproxy) for hiding the media path.

If you have any particular questions on the setup, I will try to help you.

Re: Opensips1.7 with MediaProxy

LAVerPNZ
In the incoming message to the UAC "183" can be seen: the prefix and IP
gateway.
Gateway waits INVITE from everyone.
Therefore, it is necessary at least to hide this information!!!
There is a suggestion - use the full proxy SIP and RTP traffic from the UAC.
Necessary: MGW hide behind opensips-server:
UAC(85.85.85.95)---->OPENSIPS(85.85.85.85,
192.168.0.85)------>MGW(192.168.0.11)

1. What better use for the full RTP-traffic hiding: rtpproxy or mediaproxy?
2. I need help setting: mediaproxy or rtpproxy.
3. Example configuration file "opensips.cfg" such interaction:
opensips-mediaproxy or opensips-rtpproxy.


that is for today:
[root@xxxxx ~]# ps ax | grep rtpp
17445 ?        Ssl    0:00 rtpproxy
17451 pts/2    S+     0:00 grep rtpp
30335 ?        Ssl    0:13 rtpproxy -u rtpproxy
[root@xxxxx ~]# ps ax | grep disp
17456 pts/2    S+     0:00 grep disp
30008 ?        SL     0:00 python ./media-dispatcher
[root@xxxxx ~]# ps ax | grep rel
17458 pts/2    S+     0:00 grep rel
30016 ?        SL     0:35 python ./media-relay
and opensips 1.7

eth.0 ip=85.85.85.85
eth.1 ip=192.168.0.85

4. if we use rtpproxy, then iptables configuration is needed ......
5. if we use mediaproxy then where are the config files? and how to set
them .... for the "dispatcher" and "relay".....?
6. In logic OPENSIPS not need to use checks: if the client is behind NAT
on the remote end, and vice versa - do not allow the registration of
such users!

Hi Bogdan,
Can you give us some example? 
I use opensips with rtpproxy. but when I use the topology_hiding(), dialogs not matched and OK with SDP not received to the call party and media path not established.
Thanks so.

Re: Opensips1.7 with MediaProxy

Hi, H.Yavari
To begin with, if you can - share your config please.
And, if not difficult - setting rtpproxy.
that was where to start ...
Thanks so.

Hello,

Once again, to hide the network topology from the SIP signalling you
need to use the dialog module with topology hiding:
http://www.opensips.org/html/docs/modules/1.10.x/dialog.html#id296001

On the RTP side, use any of rtpproxy or mediaproxy.

Re: Opensips1.7 with MediaProxy

Bogdan-Andrei Iancu-2
Hi.

So the 200 OK for INVITE is not matching anymore ? If so, this is not related to dialog module - the reply matching has nothing to do with the dialog module as it is done by the TM module. Maybe your problem is in a different place.

It's not safe, it's necessary to build a new wiring diagram:
(UAC      )--->sip,RTP---->(Opensips--- >rtp,SIP------>)----->MGW Cisco--->PSTN
85.85.85.85                    (85.85.85.2     192.168.0.2)     192.168.0.3

questions:
1. to hide the network topology from the users (can be used dialog module, function: topology_hiding?)
2. hide RTP traffic to MGW for Opensips-server (can be used MediaProxy or rtpproxy)?
Please, give examples opensips.cfg-file ?

reINVITE

LAVerPNZ
In reply to this post by LAVerPNZ
Hi. Please help.

scheme:
MGW <----------------- SIP / RTP -------> OpenSips
<--------------------------------- SIP --------------> UAC
IP: Network-1 Iset-2 IP: Network 1 and Network 2 IP: network-2

In such a scheme - works only SIP, and RTP-traffic between MGW and UAC
does not pass...


Can use reINVITE? then ---->

In network 1:
MGW                                    Opensips
INVITE -------------------------->
But UAC is a network-2
302 <-----------------------------
(about which user at the UAC with the IP of the network-2
............ silence ................

How to make do reINVITE MGW interface with network-2?

Either find a way to make MGWtransmit RTP on the second network, and the
first SIP....

Hi,

If the 2 network cannot route traffic directly (at IP traffic), but only
via a bridge like machine with 2 interfaces -> you need to use rtpproxy
in bridging mode in order to transport the RTP between the 2 networks.
