When i sent one campaign with over 250 contacts, over 190 calls faild! 100 calls status: "DESTINATION_OUT_OF_ORDER" 55 calls status: "NORMAL_TEMPORARY_FAILURE" 41 calls status:"UNKNOWN" 3 calls status: "NETWORK_OUT_OF_ORDER" 1 call status: "NORMAL_CIRCUIT_CONGESTION" 58 calls status: "NORMAL_CLEARING" -> some of them moved to voice mail(belongs to ext) and some other routed correctly to destination My architect to broadcast is almost funny: There is one trunk and there are two FSs. One of my FS(#1) connected to Trunk & I have created one Extension on it with user and pass(directory). Other FS(#2) has ICTDialer and plivo and makes cloud campaigns. My trunk on it is that Extension with that user and pass on FS#1! Any suggestion? I've attached CSV CDR log files.
