We swapped ISPs yesterday. We ported the numbers over to the new ISP last week but continued to use our old ISP for internet. We swapped over to the new ISP's internet last night and things seemed to be working but now we cannot receive inbound calls.
We can make outbound but not inbound. Our ISP says they didn't make any changes from last night to today. According to them the inbound calls are being blocked by our Firewall (using a Ubiquiti Security Gateway).
