Hi Maxim,
It is good to know about the rtp_cluster, but aside simplifying things,
it does not bring any new functionality - the LB and failover between
RTPproxy nodes can be done now in OpenSIPS module .
The most challenging thing we are looking at is the ability to move
calls between different instances of RTPP (for HA purposes)..or some
restart persistence for the sessions - without something like that it's
very hard to deal with SW/HW failures ; there are ways to go around for
scheduled stops/restarts (maintenance), but non for unexpected failures.
Thanks and Regards,

Brett, on the HA/carrier-grade side there is little-advertized
middle-layer component called "rtp_cluster", which in essence is
load-balancing, transparent dispatcher that can be inserted in between
some call-controlling component like OpenSIPS or Sippy B2BUA and bunch
of RTPP instances running on the same or multiple nodes. From the
point of view of that OpenSIPS it's just another RTPP instance.
And it handles all logic necessary to load-balance incoming requests
between online instances plus it can handle dynamic re-confiduration
of the cluster and track individual nodes going up and down. The code
is pretty usable, we have it deployed for several customers and it's
being actively developed as well. We have it working reliably
controlling up to 30-40 RTPP instances scattered over at least 5 nodes.

We have at least one pretty well known service provider whose name
starts with capital V using it in combination with OpenSIPS to load
balance RTP traffic via bunch of Amazon EC2 instances.

I totally agree with Bogdan. For the applications where opensips +
a RTP relay make sense, HA and persistence are much more important.
WebRTC and ICE are kinda applications in of themselves. And
although these applications are going to grow in popularity, the
"legacy" needs for an RTP relay are still massively prevalent in
the space. A general push towards "Carrier Grade", resiliency and
redundancy I think is much better for the project as a whole.
Not only that, consider that applications requiring ICE or WebRTC
will greatly benefit from HA / persistence, but not so much the
other way around :)
YMMV

Hello,
As always, the truth is in the middle.
I agree RTPP is behind on certain things (and this is why we
want to do them), but on the other hand it is a good platform
with other good features (missing on the other relays). RTPP
has better ability in individually controlling the stream
(audio /video), ability to set timeouts and onhold with no
conflicts, ability to generates events on timeout, more
flexibility in handling symmetric / asymmetric NATs, ability
to do media injection (playback), ability to do call recording
What neither mediaproxy, nor rtpengine have is a mechanism
for implementing RTP failover (for ongoing calls) or restart
persistence . This is something we want to look into. I would
love to have ICE and WebRTC on my media relay, for the HA and
persistence are more important I would say.

To be honest, i have stopped using rtpproxy for over 2 years
now. It is not evolving as fast as it should be, specially in
the context of ICE and WebRTC technologies.
I would like to suggest that opensips team should consider
adding support for rtpengine from SIPWise,
https://github.com/sipwise/rtpengine
For now mediaproxy from AG Projects is the only good choice
for handling media in opensips with ICE support (though it
still lacks WebRTC features).
Thank you.

Going for a public exposure on this question to Maxim, maybe
we will get an answer here.

Hello Maxim,
Long time, no talks, but I hope everything is fine on your side.
I'm reaching you in order to ask about your future plans in regards to
the rtpproxy project? We see no much activity around it and other media
relays are popping around.
RTPP is an essential component for us, we invested a lot of work, we
have many patches (extensions) for it (which we want to push to the
public tree, but there is no answer on this) and we are also looking for
investing a lot into big future plans (as adding more functionalities).
Now, my question is - what is your commitment and disponibility for the
RTPP project ? depending on that we what to re-position ourselves, as we
do not want to waste time and work on things which are out of control.
Best regards,
