I have a rtpproxy configuration that spawns several rtpproxy instances, using bridge mode.
An example is shown below:
/usr/bin/rtpproxy -p /var/run/rtpproxy.pid-7723 -u rtpproxy -s udp:127.0.0.1 7723
192.168.2.18/127.0.0.1 -m 10000 -M 20000
Here, rtpproxy bridges between 192.168.2.18 and 127.0.0.1 .
Now I want to migrate to rtpengine with the rtpproxy-ng module in kamailio. However, I do
not find an equivalent to bridge mode in the rtpengine command-line parameters. I see the
--ip=IP parameter, but the source code expects a single IP address, and
cannot be specified more than once. The closest I see is the --advertised-ip=IP parameter,
but I am not sure that it will do what I need.

How would somebody implement the following scenario using rtpproxy or
mediaproxy-ng/rtpengine ?
- Server with 2 or more interfaces, at least one of which is public, and at least one of
which is private (LAN)
- Public interface runs webserver that publishes web phone (SIP.js or similar) for
websocket
- Webserver runs kamailio with access to both public and private interfaces
- Websocket managed by kamailio, for SIP.js signaling
- Private interface gives access to LAN where at least one traditional SIP client (UDP
port 5060) registers with kamailio
- Phone call initiated through websocket should contact SIP client in private LAN after
proper authentication.
Can this be done at all with current technologies? How?

rtpproxy works correctly (in traditional SIP) to bridge the RTP packets from localhost

touching the (encrypted) payloads, and delegate the decryption to asterisk itself?

While my setup is not the same as yours, the fix would be to bind
asterisk to the same interface as kamailio (different port for SIP),
then simple allow rtpengine to relay to the single interface.
For the moment, I had to rework my firewall rule sets to allow
asterisk (rtp) on the public interface.

I'd agree 'drop-in' replacement is not correct. I ran into the
same
issues as you. Current there is no bridge-mode in rtpengine, I point
you to an open issue about it [1].

I think the idea behind the formulation of "drop-in replacement" is that
the module interface functions are compatible with the standard
'rtpproxy' module, so no config changes are required to make it work.
It doesn't mean that all the old features exist. It means that they are
stubbed out in such a manner as to not invalidate the existing config.
Even then, that's not entirely true, given the 'rtpengine' nomenclature
change recently.

New subject: domain not found in domain table
Hi,
We have a Kamalio a configuration that forwards calls to a freeswitch server (adding
record-route). The SIP signaling becomes successful till Kamailio receives 200 OK with
session description from our carrier. After kamailio forwards the 200 OK with session
description to Freeswitch, Kamailio drops all the ACK and BYE coming from freeswitch. From
Kamailio log we found it says,

Depending on your network setup, you should be able to allow your
private IP networks to communicate with the public address of the media
proxy by adding a network route in the right place(s). Another possible
solution could be to use the media-address= option. Certain iptables
rules (assuming you're on Linux) such as SNAT might also be helpful, or
a combination of several of these mechanisms.
