HELLO Everybody! I have a problem during installation of osmocom-analog to my computer, i am running Oracle VM virtualbox under Win11 OS. There is a syntax error while running ./configure - line 5619: sytax error near unexpected token 'ALSA' line 5619: PKG_CHECK_MODULES(ALSA, ALSA >= 1,0, with alsa=yes, with alsa=no) "make" and "make install " commands do not work. Please help me if you can, I will send you some screenshots. We appreciate your work! Greetings from HUNGARY! George

Osmocom discourse as alternative to mailing lists
by Harald Welte 27 Jul '23

27 Jul '23

Dear Osmocom community, while many people with a long history in FOSS development have no issues at all with mailing lists as primary form of engaging with their community, they have undoubtedly fallen out of fashion in favor of various chat/messaging systems or web based forums. In Osmocom, we've just launched an installation of the discourse forum software available at https://discourse.osmocom.org/ providing an alternative to our traditional mailing lists at https://lists.osmocom.org/ We're looking forward to see whether this web-based approach will facilitate more and/or other people to engage with the Osmocom developer/contributor community. Feel free to join and get the discussions started. If there's a need for more categories or sub-categories, just let one of the moderators know and we can help with that. The old mailing lists will continue to remain available for those who prefer them. -- - Harald Welte <laforge(a)osmocom.org> https://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

osmocom-analog to osmo-cc-sip-endpoint local server help
by admin＠ready100.com 01 Jun '23

01 Jun '23

osmocom-analog is working. osmo-cc-sip-endpoint is installed and working (i think) however, i'm not sure what my sip-endpoint command line should be... Everything is running on the same machine, I just want to connect my AMPS device to my local asterisk server. I have setup a user for the pbx using the phone number baked into the phone. I have a non standard port (ie not default) for my asterisk server. When I try to use command lines I've seen on the lists I just get: sip.c:1783 error : Failed to create SIP stack object I assume it's just because I have incomplete parameters. Can anyone help? I'm so close!

Is there any good cheap full duplex sdrs for amps?
by stubbertville＠hotmail.com 05 May '23

05 May '23

Howdy! Im new to all this and I already have two AMPS cell phones, but I cant seem to find a cheap sdr I could use with them, the hack rf and lime sdr are either waaaay too expensive or waaaay too rare, any suggestions or help would be welcomed and appreciated!

Hi all, thanks for all your help so far! I believe I have successfully built sofia-sip and osmo-cc-sip-endpoint. I did have an issue building osmo-cc-sip-endpoint as it was complaining about using AC_CONFIG_MACRO_DIR more than once in configure.ac when running autoreconf. I saw that it was defining both AC_CONFIG_MACRO_DIR and AC_CONFIG_MACRO_DIRS so I commented out the latter and everything seems to have proceeded fine afterwards (though with warnings). I'm leaving this note here in case someone else faces this. I'm running Ubuntu 22.04.2 with everything up to date so I'm guessing the build dependencies have become more strict towards this. I am running amps with: $ amps --limesdr-mini --channel 334 - channel 332 -o --fast-math I am running osmo-cc-sip-endpoint with: $ osmo-cc-sip-endpoint --local 192.168.3.225 --remote 192.168.5.228 -R 8927188(a)192.168.5.228 -A 8927188 secretpasswordhere 192.168.5.228 -v 0 * osmo-cc-sip-endpoint connects to my asterisk server at 192.168.5.228 just fine and it also reports it is connecting to my local ip via the socket amps sets up. The issue I'm facing at the moment is that I'm not getting audio from asterisk coming out of the earpiece on the amps phone. I do hear a bit of white noise and an occasional click (interference I'm guessing) and I know the phone is otherwise good because I used it to call another phone through amps. Based on the asterisk logs, everything looks as it would for any other hardline I have connected but I'm not hearing anything. I'll do some more checks later to make sure asterisk is behaving properly and I'll try to call my amps phone from a hardline and see if there's some sort of one-way audio issue. Does anyone know if osmo-cc-sip-endpoint needs a specific audio codec? I'm only allowing ulaw right now, though I also tried with both ulaw and alaw enabled and noticed no difference. To answer Jordan's question about how I compiled the osmocom-analog-binaries, these are the steps I used: $ autoreconf -if $ ./configure $ make -j4 $ sudo make install I think I'm really close, just not 100% there yet.

What codec is your asterisk server set to use? You may need to play with the allowed codecs on that end. I remember running into that issue before as well however I do not remember how I went about resolving it. I will be able to play around with my setup again later this weekend and I can let you know how I had mine configured. You may want to ensure under your Asterisk SIP Settings tab that you have ulaw, alaw, and gsm codecs enabled/allowed to start with. You may also be able to specify the codec in the sip connector parameters. The last thing I can think to mention is to ensure your SIP traffic is flowing freely to both ends, SIP through firewalls can be a huge pain in the rear end.

SIP connector for osmocom-analog?
by Famicoman 22 Feb '23

22 Feb '23

Hello all! I have been enjoying osmocom-analog with my AMPS phones for the last few days and was wondering if there has been any work done for SIP connectivity with analog phones? I see there is 'osmo-sip-connector' software from my searches but as far as I can tell, there is no similar software of osmocom-analog. Thanks, Mike

Paging problem with osmo-cc
by Dave 07 Feb '22

07 Feb '22

Hi All, I have an issue where paging doesn't work when using osmo-cc-endpoint with tacs and a USRP1 I can place calls from the MS out over osmo-cc-endpoint via my pbx to the pstn with no problems, if I try to call back in via sip it always fails to page the MS Running the -x option I can call between two MS stations with no issues, paging works and the calls connect Here is an example if I run the command I can make calls from the mobile device and hear the music, I can also press d and call the MS back with no problem, paging appears to work 9/10 times ./tacs --sdr-uhd --channel 323 --channel 318 --channel 320 --samplerate 581818 --sdr-tx-antenna TX/RX --sdr-rx-antenna RX2 2342123456 amps.c: 932 info : (chan 323) Call to mobile station, paging station id '2342123456' amps.c:1186 info : (chan 323) Paging the phone frame.c:3693 info : (chan 323) RX Level: 79% Quality: 80% Polarity: POSITIVE amps.c: 832 info : (chan 323) Paging reply 2342123456 (ESN = removed, Class 3 / Continuous / 20 MHz, TIA/EIA-553 or IS-54A mobile station) amps.c:1170 info : (chan 323) Assigning channel to call to mobile station here is the output with -o and an inbound call via sip endpoint.c: 931 info : Handle message CC-ATTACH-REQ at state IDLE (callref 2) message.c: 516 info : IE_CALLING_INTERFACE name='sip' message.c: 588 info : IE_SOCKET_ADDRESS address='127.0.0.1:4201' endpoint.c: 390 info : Remote peer with socket address '127.0.0.1' and port '4201' and interface 'sip' attached to us. endpoint.c: 394 info : Changing message to CC-ATTACH-CNF. endpoint.c: 931 info : Handle message CC-ATTACH-RSP at state ATTACH-SENT (callref 1) message.c: 516 info : IE_CALLING_INTERFACE name='tacs' message.c: 588 info : IE_SOCKET_ADDRESS address='127.0.0.1:4200' endpoint.c: 308 info : Attached to remote peer "127.0.0.1:4201".
