Obiha 110 as an FXO port for failover using freepbx distro

have anyone have any luck on this yet?

i follow the wiki on freepbx and it work. However when the we loose internet connection neither inbound or oubound would go to obiha 110 as a failover.

I reach out to commercial support but didnt get far with them,… i am hoping someone on here have done it before.

thank in advance
