I also still strugling with no luck. I have a very good understanding of the openbsc and it works well as the NITB.

But LCR and asterisk integration is no where closer.

Im using debian 6.0.4

OpenBSC, Osmocore, Osmo-abis : latest git clone

LCR : latest git clone

mISDN : downloaded from the site

First thing didnt aligned with documentation is the LCR patch doesnt seems apply. I assume the developers has made the patch into it, so its not applying. But when i inspect the source of gsm_bs.cpp, doesnt seems there either.

Passing on - once LCR compiled with asterisk and gsm_bs, it doesnt even create a gsm.conf

So almost no go from that point.

Anyway, now im waiting for some feedback about the actual topology of it since its unclear whether we still need E1/ISDN in the middle to integrate this. If that is the case i wouldnt want to try that. Been all IP solution, there is no point having TDM in the middle at all.

Do you have any idea about that ?

I think im little bit lost here now the way it should work. As per this link it only works with isdn interface not sip.

All im trying to do is,

[MS]---[nanoBTS]----[OpenBSC NITB]---(ip)---[LCR]---(ip)---[Asterisk]----(sip)--->

Is this what its been made for or are there any E1/ISDN interfaces in the middle.
