I have no problem with Astra 12207-V, but my guess is that the problem is CI
related. The CI code in the firmware is old and buggy and I don't
think anyone is going to fix it. Convergence has moved their CI
handling out of the firmware with only mininmal hooks to the CI hardware. 
I don't know what plans they have for releasing any of the code, binary or the
API hooks. In the case of the API they could release a different
firmware which would need a userspace CI stack (transport layer
upward, the rest would be handled by firmware and driver).
