Hi Guys,
I have a serial caller who calls our tollfree line xxxx but when I check the logs the number is not showing.
how can I unmask the number or reveal the number so that I can block or prevent this from happening.
the call come through as our Outbound CallerID (Dadhi Trunk) xxxxx.
see logs below below
