Hi List
I want to use OpenBSC with Asterisk and LCR. After a lot of reading I found out that openbsc must start with the Paramters "-m" and "-P". But i got a lot error messages like:
<0006> gsm_04_08.c:2960 receive message GSM_TCH_FRAME <0006> gsm_04_08.c:2992 TCH frame to lchan without RTP connection
So i tried a lot and start only with -P and the RTP-Proxy started. But LCR and Asterisk sure not involved because the missing "-m". So i need "-m".
It is a bug or a feature that "-P" will be ignored if I set "-m"? I´m sitting over the bsc code but until this moment I didnt found something so I hope somebody here can help.

Hi,
where did you find that information? The RTP proxy is only useful if you have two BTS and want to be able to do handover between them and don't have someting like LCR running.
Hi all,

I actually think the proxy has to be active, since only then the OpenBSC ever sees the RTP frames from the nanoBTS (and can hand them via MNCC into LCR).
The "rtp proxy" command option should decide if the RTP streams are rounted directly between BTSs, or if they are routed via OpenBSC.
So for a LCR setup, I'm quite positive that you would have to use "-P"
@netzing: I honestly don't have time right now to try to reproduce the setup, way too much work overload. Sorry.
Hi List
I´m really sorry! After I write this E-Mail,I checked out the the git log from lcr and see that it makes changes to work with the current Osmocom-BB. But i hadn´t the current Osmocom-BB and so messages from lcr never reached openbsc and I thought the RTP-Proxy doesn´t be active and the reason for my problems.
But thanks for the quick responses!
Have a Nice Day
