Hello! I Need Help I install these three programs OpenBTS, OsmocomBB, Asterisk Then run them, Everything works well OpenBTS sent an SMS to my phones I answered and he checked me I registered into OpenBTS a second phone I tried to transfer SMS between phones - all good but when I try to call from one to another I did not get Asterisk writes ================================================================ *CLI> Retransmission timeout reached on transmission 755803415(a)127.0.0.1 for seqno 179 (Critical Response) -- See wiki.asterisk.org/wiki/display/AST/SIP+Retransmissions Packet timed out after 32001ms with no response ================================================================ Why?

Osmocombb as a Zombie
by Duarte 09 Jun '17

09 Jun '17

Hey guys, first of all I want to express my deep respect for this project, this is truly amazing project and very well developed. Second, I'm doing a few studies regarding GSM security (no, I'm not hacking.) and I need to develop a feature for osmocombb, which is: the ability to turn the L23 app as a zombie (C unix domain socket) waiting for instructions (e.g.: connect to the network with predefined parameters (IMSI), collect RAND, send sms,...). Is there any documentation or flow regarding the code? It's very hard for a non C coder to follow the flow... Or is there someone that can help me in the Architectural level? Thank you.

As I understand, you want to connect the network you running yourself on OpenBTS. There are two modes of network selection: manual and automatic (when MCC/MNC from SIM card are used). Have a look at the 'network-selection-mode' in your config file (~/.osmocom/bb/mobile.cfg). Also, have a look at the 'network' command in VTY. You can also create a virtual SIM card in your ~/.osmocom/bb/mobile.cfg (look at the 'test-sim' section) with desired IMSI and RPLMN (001 / 01 by default). Then you will be able to attach one using the 'sim testcard 1'. With best regards, Vadim Yanitskiy.

OsmocomBB MNCC socket implementation without LCR
by Gerard Pinto 29 Mar '17

29 Mar '17

Greetings, I have been working with Layer23 stack of OsmocomBB since a couple of months. I decided to try MNCC socket interface without LCR (I'm aware there is an implementation embedded in LCR gsm-ms). I reverse engineered and wrote a simple C application taking mncc.h. Problem: I'm unable to make a call on live network, although it does channel allocation, ciphering etc. Flow: 1. Create MNCC struct and write on to the osmocomBB socket 2. OsmocomBB parses it well and request for channel, ciphering mode, init MM, sending SETUP etc works great. 3. However, in response to step.2 after sending SETUP it returns with (ms 1) Received 'RELEASE_COMPL' in CC state INITIATED. Why does it release CC? 4. I further debugged, the reason for release is in fn. gsm48_cc_rx_release_compl in (gsm8_cc.c) it says mncc-cause = *GSM48_IE_CAUSE*. with no description. I really don't know whats causing this issue. Any help would be much appreciated. Or It would be very kind if someone could guide me. My mncc socket create code: struct gsm_mncc *mncc; int i = 0; int call_ref = new_callref++; mncc = create_mncc(MNCC_SETUP_REQ, call_ref); if (!strncasecmp(number, "emerg", 5)) { printf("Make emergency call\n"); mncc->emergency = 1; } else { printf("make call to %s\n", number); mncc->fields |= MNCC_F_CALLED; if(number[0] == '+') { number++; mncc->called.type = 1; /*international*/ } else { mncc->called.type = 0; /*auto-unknown -prefix must be used*/ } mncc->called.plan = 1; strncpy(mncc->called.number, number, sizeof(mncc->called.number) - 1); printf("Calling number %s\n", mncc->called.number); /* bearer capability (mandatory) */ mncc->fields |= MNCC_F_BEARER_CAP; mncc->bearer_cap.coding = 0; mncc->bearer_cap.speech_ctm = 0; mncc->bearer_cap.radio = 3; /** Support TCH/H also*/ /** Supported rates **/ mncc->bearer_cap.speech_ver[i++] = 2; /* support full rate v2 */ mncc->bearer_cap.speech_ver[i++] = 0; /* support full rate v1 */ mncc->bearer_cap.speech_ver[i++] = 1; /* support half rate v2 */ mncc->bearer_cap.speech_ver[i] = -1; /* end of list */ /** END **/ mncc->bearer_cap.transfer = 0; mncc->bearer_cap.mode = 0; /* CC capabilities (optional) DTMF */ mncc->fields |= MNCC_F_CCCAP; mncc->cccap.dtmf = 1; mncc->fields |= MNCC_F_CCCAP; mncc->clir.inv = 1; mncc->clir.sup = 1; } return send_and_free_mncc(mncc->msg_type, mncc); Looking forward to the reply, Thanks, Gerard -- View this message in context: http://baseband-devel.722152.n3.nabble.com/OsmocomBB-MNCC-socket-implementa… Sent from the baseband-devel mailing list archive at Nabble.com.

ARM Core and UI
by Anton Gorbachev 29 Mar '17

29 Mar '17

Dear Osmocom members, I am new in OsmocomBB but trying to understand how all the stuff works. And I have a question. As I understood we have DigitalBB Calypso in our Motorola phones which consist of DSP and ARM Cores. If we are talking about "normal" phone firmware, In DSP L1 processing is done, in ARM core L2 and L3 processing of GSM stack is done. But we must also have some "regular" OS somewhere, am I right? So I mean all the menus, applications like "Settings", "Phone book", etc. In modern phones, I believe Adnroid or iOS communicate with some RTOS running in ARM core of DigitalBB. But what is about Motorola phone? Does it have separate ARM processor/RAM for a refular firmware? Did you create some applications for ARM part of DigitalBB and some applications for UI which run outside the RTOS? It's possible that I am confusing with all the terms but I would appreciate if you help me to understand. Kind regards, Anton

Connecting OSMOCOM to OpenBTS
by Usama Muneeb 26 Mar '17

26 Mar '17

I recently set up OpenBTS which is working perfectly. I can make a test call by calling 2600 using an Android phone. However when I try "show subscriber" in OSMOCOM, various BTS are listed, with their MNC and MCC values but OpenBTS is not listed. Any solution to this? P.S. I've determined the MNC and MCC values for OpenBTS which are 001 and 01 respectively.

git.osmocom.org cgit improvements
by Harald Welte 20 Mar '17

20 Mar '17

Hi all, today I've deployed some cgit improvements on https://git.osmocom.org/, in the hope that it makes this tool even more useful: 1) syntax highlighting of source code (requested by Hoernchen) The source code is now highlighted by pygments. I don't really understand why somebody would want to look at source code a lot in a browser, but well, it was as easy as to enable the existing pygments based filter plugin. 2) rendering of "about" page from README.md As you might have noticed, I've introduced a README.md in a number of repositoires, and cgit is now rendering an about page for every repository, e.g. at http://git.osmocom.org/libosmo-abis/about/ 3) gerrit change-ID hyperlink generation All gerrit Change-IDs in commit messages are now automatically converted to hyperlinks to the respective gerrit change, see e.g. the below example: http://git.osmocom.org/openbsc/commit/?id=6dd0fc685b7149f67a5fe17a5bce55c44… Please note that this works for the "Change-Id" line of the actual change, but also for change-ids in the free text (e.g. "this depends on change-id ... in libosmocore") 4) Osmocom ticket/issue hyperlink generation Any Line that matches the "^((Relate|Close|Fixe)[ds]):" prefix is scanned for occurrences of "OS#(\d+)" which are then amended with hyperlinks to the respective issue on osmocom.org Please note the OS# prefix is mandatory, so things like "OS#1614, 1615" will not work, as can be seen at http://git.osmocom.org/osmo-pcu/commit/?id=0a8fae8d141c2cfa4387ffe9b35402d5… Please format your commit messages accordingly.
