> This is happening on a FreePBX system, but as it's an Asterisk issue I am posting it here. In FreePBX I have a ring group configured that initiates nine outbound call legs. Calls come in over a Digium PRI gateway which inserts an invalid UTF-8 string "▒" in front of the Caller ID name, e.g. '▒2126564615', which crashes Asterisk.
> I am getting below error/backtrace on all of the outbound call legs Asterisk wants to initiate and then Asterisk crashes with 
> "Disconnected from Asterisk server
> Asterisk cleanly ending (0)":
> Got 22 backtrace records
