Sangoma W400 GSM NOT Work

Hello to everyone,
Does Sangoma W400 GSM digital card works with latest freePBX distro (Asterisk 16)?
I found some response to this question that it is not supported?
How it is even possible? And why? (Please give some technical reasons not commercial or “it is just the fact”).
At my custom VoIP server i have one OpenVox A800P analog card, and one Sangoma W400 GSM card. The first one are older and it is working well thus second one don’t work.
Please, if someone have solution to make this card to work and can share solution i will be very tankful.

Here some technical info about deployment

I would imagine the drivers are no longer being maintained for that card. It went EOL in 2017 and support in 2018.

OpenVox A800P is much older than Sangoma W400 and it is also EOL EOS etc.
Despite that, OpenVox support make it work with dahdi 2.11.1 !!!
It is very disappointing that Sangoma and community also make decisions based on profit and not by technics. Sangoma’s hardware should be supported and platform backward compatible!
In my opinion only acceptable reason can be that kernel on newest version of freepbx don’t support this card. And my technical question is why? What is that on newest kernel that is not supported?

I think you are a little confused, there is a difference between backwards compatibility and ongoing support. The reality is there is probably nobody left in engineering at Sangoma that has any idea on this card and the reason it went EOL is because the uptake of these cards was minimal (I’m ex-Sangoma so I remember the discussions) whilst there are a lot of decisions I don’t agree with, trying to provide engineering support for a card that is at least 5yrs old minimum and probably a handful of these cards that are still in use doesn’t make sense in any way.

Ok. if i understand you well, nobody works on to support this card?!
That doesn’t mean that it is not possible that this card works on SNG7 and Asterisk 16 !?
If that is the case, maybe someone from community is capable to provide answers and solutions.

Libwat would have to be updated for newer kernel and dahdi requirements and that open source project has not been touched in 7 plus years. This is not a FreePBX problem. Get someone to update that package to be compatible and the card should work.
