Asterisk crashes (Freepbx 12.0.25 Asterisk 11 with Sangoma W400 GSM and BRI Digium)


I’m having asterisk crashes (kernel: asterisk[6985]: segfault at 8 ip 000000000058bcbf sp 00007f4c6cecf490 error 4 in asterisk[400000+22e000]).

I had this hardware configuration with Elastix and I only managed to have a stable system without using the Sangoma W400 - I discovered the problem with sigwat but I couldn’t build a stable solution that wouldn’t crash with a specific call condition - I format the disk and installed the last release of Freepbx - the first test I made with Freepbx for that call condition the asterisk didn’t crash but after entering in produtction it’s still crashing and so far I didn’t figure where and why.

Could someone provide me some help to figure a stable solution to use the Sangoma W400?
