Hi,
I just managed to compile and install it, but I had to struggle during compilation, I got these:

I solved it by applying the linker switch:
-Wl,--allow-multiple-definition

Hi,
Issues/Limitations:
- probably, we should also do some more/heavy Loadtesting, even though
it was thoroughly tested
- fix some compiler warnings ;-)
- as Carlos mentioned: The DTLS stuff....
Those are the issues/limitations, i am aware of.
Thanks, Carsten

Hi Carsten,
we are interested in this plug-in. Do you have any experience with RTPengine using this feature? I mean, did this plug-in work fine with RTPengine 3.3? Is this plug-in fully functional despite the fact that it does not work with recent RTPengine versions or are there any known limitations/bugs/missing features?
I don't know if any part of the code was modified to add/remove features, but if it is exactly as it was originally implemented, it works fine with rtpengine 3.3 and the only (and important) limitation it has is that it is unable to restore DTLS connections.
This, somewhat important, limitation is due to my lack of knowledge on the matter, but it shouldn't be difficult to implement for someone that is knowledgeable on the subject.
Regards, Carlos
We recently added some features to the RTPengine project and thus are working with the master branch. Because we also need this redundancy feature, we thought about implementing it all by ourselves. We didn't know about your project, but we eventually would bring the time to bring this plug-in up-to-date. So your mail came just in time :)
Greetings, Paul
You mail came just in time :) .

Hi everyone,
several months ago, we've implemented a plugin for RTPEngine to synchronize it with a REDIS-Database. This allows RTPEngine to operate in a HA, as you can restart RTPEngine and/or make a failover to another machine with the same IP (e.g. using Heartbeat or similar), WITHOUT LOOSING ACTIVE SESSIONS.
This enhancement was originally implemented by Carlos Ruiz Diaz.
Due to lack of time, it still requires RTPEngine 3.3 and needs an update, to work with later versions.
It can be found here: https://github.com/ngvoice/rtpengine-redis-plugin
If anyone is interested in contributing to this extension, please ping me and i will happily add you as a contributor.
Thanks, Carsten
