In case it's of interest, please see https://osmocom.org/projects/foss-ims-client/wiki/VoWiFi_wit... for an existing way how to talk to VoWiFi carriers from entirely free/libre/open-source software. It's basically a hacked-up version of Asterisk that has IMS client support, plus a modified strongswan IPsec client.

I've played with doubango for some time trying to get it to work against the flavor of IMS used in VoLTE / VoWiFi, and it is not all that close to it, even with various hacks applied from https://gitea.osmocom.org/ims-volte-vowifi/doubango/commits/... in which I tried to add a Linux kernel IPsec plugin as well as various other bits and pieces.

I've met few people with a similar decades of dedication to helping and supporting users, particularly newbies, to work with FOSS. You must have an incredible patience to do that. I never shared that quality, so maybe that made me notice his gift/dedication even more.

After Joerg 'schily' Schilling passing last year, with Sven Guckes another of the "Berlin FOSS old guard" has passed in a rather short amount of time. Both way too young.

RIP, Sven.

If you have so many comments, why raise it here and not mail the contact stated at the website? Do you think it is more productive in effecting a change to only post this here, rather than to whoever is responsible?

correct, the design is E1 only. No T1/J1 support, sorry.

Indeed, interfacing legacy GSM base stations is the primary use case. However, you can jsut as well use it to interface any other type of E1 equipment, like PBXs etc.

Please note that the icE1usb in its final incarnation with the FPGA based approach was almost entirely done by Sylvain Munaut, not myself. So please give credit to him, and not to me. I only contributed a bit in testing, some patches here and there in the firmware, and the new experimental DAHDI driver for it.
