osmocom-analog to osmo-cc-sip-endpoint local server help
by admin＠ready100.com 20 Apr '26

20 Apr '26

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!

SIP connector for osmocom-analog?
by Famicoman 15 Apr '26

15 Apr '26

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

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.

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."
