Dear List,

this is the first post to this list, just to get the discussion started and to let you know that there has been good progress in recent weeks on the Osmocom Community TDMoIP network. We have a prototype network as can be seen in the diagram at https://osmocom.org/projects/octoi/wiki/Community_TDMSS7_Network#Currnet-Net... - primary users so far are manawyrm in Kiel/Germany and myself in Berlin/Germany

Via the Portmaster3 one can dial into a variety of BBSs (the portmaster forwards via Telnet based on the called number), see https://www.ckts.info/directory/europe/continent/ (search for Germany / 30 / 12343xxx) for the current listing.

ISDN data calls are quite stable, even through the remote TDMoIP.

For analog modem connections (at least V.9x) via TDMoIP, we need to resolve the proper handling of packet re-ordering (https://osmocom.org/issues/5432) as we see a few of them and they tend to be rather destructive.

We definitely need a lot more testing and the experimental osmo-e1d based code for the protocol needs a lot of improvements for wider deployment, but things are coming together rather nicely.

In case anyone has ISDN PRI equipment and wants to connect, feel free to reach out.

Regards, Harald

p.s.: #retronetworking on libera.chat is where most of the communication related to this project is happening.
