Problem with RTP-Proxy

Hi, list!

We are trying to connect OpenBSC and Asterisk together (through LCR), but we have many problems. We start OpenBSC with the parameters -P -m --debug=DRLL:DCC:DMM:DRR:DRSL:DMNCC:DMSC:DNM:DLCH:DMUX:DHO

Now, if we try to call a mobile phone from another one, we get many errors:

<0006> gsm_04_08.c:2960 receive message GSM_TCH_FRAME <0006> gsm_04_08.c:2992 TCH frame to lchan without RTP connection

Now, if I understand what mncc_tx_to_cc does, I can just think, that the RTP-Proxy is NOT active, but a part of OpenBSC thinks that it IS active.

Another interesting problem is, that, although we start OpenBSC to debug the CC, we do NOT get a message like:

Setting up TCH map between ...

(gsm_04_08.c line 1606)

Could someone confirm me my idea? And, maybe, give me a suggestion to fix our problem?

We use OpenBSC in the version 0.9.11.375-ca8f.

Thanks a lot in advance for your help Luca Bertoncello
