I have a simple setup with FreePBX 15 and 5 Cisco 7961 phones.
Time by time inbound route it is not working, phones in ring group are not ringing (caller phone show the call pickep up and play nothing but silence).
In order to restore it I have to set destination to one extension (usually mine) and then back to the ring group.
Rebooting the machine does not fix the problem, only the procedure mentioned above.
I’m not an expert with FreePBX, do somebody has suggestions for me?
