Well, after some time testing i discovered that the current version of jigasi has a bug that afffect the incoming calls from asterisk (don know about other). if you want that working you have to use: apt-get install jigasi=1.0-235.
Many people reported this but i found no other solution in here (sorry if im wrong…correct please).
The current version do not answer so no incomming calls.
You have to use asterisk version 13 or > one that compile with opus codec.
Hope this helps someone out there.
