[Freeswitch-users] suppressed callerid number

Just a thought to bear in mind, this'll only work as a casual block.

Over SIP the caller is free to send anything they like, which means your
customer's could easily send something fake to avoid the block. And many
pure-VoIP callers won't have any sort of CallerID at all.
