I am having outbound calls failing when an inbound call is active. My setup is as follows:
FreePBX 12
Asterisk 11
Server is virtualized in house
Behind a firewall with public IP assigned to FreePBX server
I have tried turning NAT off in both Advanced Settings and at the extension with no change in behavior.
Multiple outbound calls CAN occur successfully simultaneously.
I don’t know where to go from here.
Thanks in advance -
Adam
