We are running FreePBX 13.0.182 with Asterisk 11
Our outbound route has multiple trunks for overflow but when calls fail with SIP 404 the calls do not overflow. Any way to fix this? In the past it did overflow to the next available trunk. I even confirmed this on an old FreePBX 2.9014 system Asterisk 1.87.
