I’m running v14 freepbx. It’s been running very for number of years. Suddenly all the incoming calls are going directly to voicemail. Looking at the asterisk errors, it said “WARNING[2406]: res_pjsip_registrar.c:1189 registrar_on_rx_request: Endpoint ‘anonymous’ (57.128.170.255:59156) has no configured AORs”. Asterisk info status “offline” to all my extension. No idea why!!
I have reasons to believe my ISP have started port filtering. I suspect port 5060 and 5160 are being blocked It’s new my ISP. How can I verify this theory?
