I have to DX2030, in the origin side I take all the call from the specific DNIS from the PSTN side and translade to send it over IP to the destination. My problem is I recive some fakes calls and I want to block it in the origen or in detination. In destination the call are routed from the IP to Line side (PBX)
exist any way to block an specific incoming number? the caller id is showing in the monitor.
