HT818 - Outbound working. Inbound isn't working. Tried different ports - Status says "Ring" but nothing. Analog phone


As the title states. Nothing complex here. Replacing an old Grandstream GXW4008 that died.

All FXS ports are registered to freepbx. I can pick up the handset and make outbound calls no problem. Once I try calling inbound, the phone doesn’t ring. If I pickup while seeing the status go to ring - Nothing. Call isn’t answered on the other end.

Not sure where to look. Any ideas?
