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 [1] 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@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.

Cheers, Mike

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 -- osmocom-analog mailing list -- osmocom-analog@lists.osmocom.org To unsubscribe send an email to osmocom-analog-leave@lists.osmocom.org

That connector does indeed work with Osmocom-analog, it can be a bit

tricky with the lack of documentation however, I have navigated it before and would be happy to lend a hand. Can you tell me about how you compiled your osmocom-analog binaries (what options and such used)?

Glad to hear you are getting there! 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.
