I’ll use this thread to announce the individual RetroNetCalls.
Today, I’m happy to announce the next incarnation of RetroNetCall, the retronetworking oriented spin-off of OsmoDevCall
This time, there’s no formal presentation. However, if people are interested, laforge can report on the ISDN_at_CCC_Camp_2023 which jolly and laforge operated last month.

I had this so much on my agenda, but for personal reasons I was not able to attend 
Has the call been recorded?
It was not.
And now a useless sentence because apparently posts on discourse can’t be less than 20 characters …
It is a configurable setting, and I just reduced it to 10 characters on any but the initial post. As a site admin, you also have access to those settings yourself, btw!

This time, @laforge (and maybe some others) will give a tour of divf, the central office of the OCTOI network based on yate + dahdi-trunkdev
We’ll look into how subscriber E1 terminate in osmo-e1d + dahid-trunkdev, how that feeds into yate, how the routing/dialplan works, as well as the new SS7/ISUP interconnects to the two EWSD.

I kindly ask this meeting to be recorded; I already have an appointment tonight which I cannot shift and it would mean like a nice santa clause gift to me that I can gather the information later on 
Yes, usually all of them are recorded - unless they are super informal without any actual prepared presentation. It will usually take some weeks until they are cut + published by @tnt - who has just moved to a new home, and hence I expect it might even take a bit longer due to that.
Meanwhile you can normally find the raw video at RetroNetCall - at least after BigBlueButton has published it there, which can be a number of hours after the meeting ended due to internal post-processing.
Yesterday, I finally found the time to watch it. Thank you very much for the comprehensive and interesting insight into OCTOI’s engine room.

This time, laforge will give a brief look decoding Telefax G4 protocol traces, as he recently acquired one of the few G4-capable fax machines, a Canon_FAX-L260i. G4 is the digital-only version of Telefax that works without a modem, directly over the 64k ISDN B-channel.
We’ll look into the ITU-specs of Group 4 Facsimile Service as well as at an actual B-channel protocol trace taken a few days ago.

This time, we won’t have a presentation but intead a joint, collaborative session where we’re analyzing and debugging any potentially remaining (or new?) issues with divf.retronetworking.org, our central soft-switch of the OCTOI community TDMoIP network. Participants are invited to try making certain calls and we will look at logs/traces and see what we can fix or improve.
