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.

Hi Andreas, It was apperently compiled on my debian while i had misdn libs isntalled. Now im trying on a fresh debian from the same set of sources which i got it working and without misdn, it fails to compile gsm. Attached is my config output and compile break. http://pastebin.com/W6UHn4Lc So should i still install misdn even though its not used.

Hi Andreas, is the LCR actually transcoding gsm-fr to alaw towards sip side ? Rgds Nik On Wed, Mar 7, 2012 at 3:17 PM, Nik Pakar <nikpakar(a)gmail.com> wrote:

Nik, You could check whether this is PCMA or GSM-FR with RTP stream bitrate. Capture the stream with Wireshark and look at RTP payload size or use a voice call information dialog (Telephony->VoIP Calls). PCMA bitrate is 64kbit (often 160bytes per 20ms), while bitrate GSM-FR is 13.2kbit (usually 33bytes per 20ms).

hi nik, since lcr uses alaw (optionally ulaw) internally, it transcodes the audio between alaw and gsm full rate. alternatively you can bridge rtp directly between freeswitch and openbsc, if you use the "bridge <interface>" feature at interface.conf. additionally you need to add a line "rtp-bridge" to your interface definition. this rtp-bridge feature only works with the bridge feature, since lcr will not be able to handle audio streams then. since it is still developed, you need to use the "jolly/rtpmux" branch of openbsc. then it will only offer the codec to freeswitch which the phone supports. on the other direction, lcr selects the commonly supported codec. if more codecs are supported, the upper most (prefered) is used. anyway it should work in both cases. (with and without rtp-bridge feature) regards, andreas

no, you need most of this branch, because the patch affects the mncc-interface between openbsc and lcr, too.

There is amazing material about Git online so you have absolutely no excuse for not trying much harder on your own to accomplish what you are obviously getting paid a lot of money to do. Did you already look around, or are you asking (i.e. expecting) others to help you without trying to find the answer on your own? That is quite unacceptable and will make people hate you, because as you know everyone is very busy with other things than educating you about git. I think you understand this. I strongly recommend http://progit.org/book/ which has very good coverage of git, and is easy to read. You can't expect any success whatsoever in a project where you are new to the development tools, if you aren't willing, eager and able to learn those tools. You will just make people angry in general and angry with you in particular. You must understand that open source communities are a completely different social construct than what you may be used to from commercial customer/supplier relationships. Your behavior on this mailing list (and apparently others) is as if the open source community was a commercial supplier to you and you are rapidly making one faux-pas after another, which naturally results in an incredibly bad standing for you within the community. If you are going to be successful in using an open source component then you must change your mindset and become a part of the community. The only way to do that, really, is to contribute something. //Peter

Hi Andreas, extreamlly sorry for the blind question. I didnt do autogen to create the configure. Extreamly sorry again. Rgds Nik On Mon, Mar 5, 2012 at 10:19 AM, Nik Pakar &lt;nikpakar(a)gmail.com&gt; wrote:
