I'd be curious to know if your performance might actually be higher, owing to improved
CPUs since the study was done, hyperthreading, more frames per NIC interrupt, etc.

Yes, they usually applied even for superuser, and yes - this should

There's another rtpproxy replacement which is compatible with kamailio's
rtpproxy module (no configuration changes needed in kamailio)
This one is threaded, works in kernel space with userspace failover and shoud
improve rtpproxy's performance.
At the moment there are binaries only for debian amd64 but you could compile it
yourself if you're interested in testing it:

Hi Jon,
questions:
- Can i also use it for IPv4/IPv6 Translation and Bridging? I did not
find any internal/external ip-Parameters as in the old RTP-Proxy
- Does it also support the basic media functions, such as recording
and playback?
- Are the sources somewhere available?
Thanks,

We use the internal and external flags for slightly different purposes:
to make a distinction between IPv4 and IPv6 in the initial offer.
Mediaproxy has no notion of an internal or external interface, but needs
to know whether to return an IPv4 or an IPv6 address for the INVITE. So
we use the "I" and "E" flags for the calling and the called party to
specify whether that endpoint is on IPv4 or IPv6, respectively. It's
really only needed for the called party, but hey, why not keep it
consistent if we can, right?

Hi Richard,
i've noticed the use of the i and e flags for your mediaproxy implementation.
Right now i'm testing a minor patch for the RTPProxy module to allow
automatic selection of "ie" or "ei" just for this use case based on
the media-ip type (e.g. always set "ie" if you have an IPv4 address in
the SDP, always set "ei", if you have an IPv6 address).

This may work if those use cases are the only ones you're going to run
into, but here we also use it for the "II" and "EE" cases, i.e. all
calls and not only those where v4/6 translation is required. This is
especially important for IPv4 NAT traversal.

Hi,
short question:
The provided Debian-Packages are Version 2.0.2, while the source (and

I hope, that minor change wasn't a major bug-fix? ;-) Are there any

Hi Jon, Hi Richard,
i wanted to say thankyou for this great piece software!
I installed it on a Intel Atom Server (x86) last week, which is
working as a P-CSCF in the Point-of-Presence (PoP) of a customer.
Perfect! I'll make some loadtests on that system next week and i'll
let you know the results.
However, some questions remain:
- any update on the 2.0.2 sources? This URL
http://deb.sipwise.com/spce/2.6/pool/main/n/ngcp-mediaproxy-ng/ still
has only the 2.0.1 sources...
- is there a changelog availabe somewhere?
- i haven't looked at the sources, but can i query the RTP-Stats in
Release 2.0.2 ($rtpstat as in rtpproxy.org)? I get an error from the
ngcp-mediaproxy-ng, if query for the RTP-Stats...
Kind regards & thank you,
Carsten

Hi Carsten. The problem with the source and bin packages has been solved. They
are back in sync. You can apt-get source ngcp-mediaproxy-ng to get the source
or download it from
http://deb.sipwise.com/spce/2.6/pool/main/n/ngcp-mediaproxy-ng/
I "promise" (hopefully as it does not depend on me 100%) that we'll have
the
github-jenkins-automated_tests glue ready by the end of the year (after our 2.7
version has been released) so the code will be available in github in a much
more accesible and open way.

The changelog is installed through the debian packages in

in the ../debian/changelog file.

That command isn't currently implemented, but it should be fairly easy
to do, so I'll see if I can include it in the next version.
