Any customer with a PBX has a valid reason to pass CLI that isn't theirs if they are passing through a call.
Hi Dovid, For example, Vonage implementing Simultaneous Ring, you want to see the original caller id on your cell phone, not your vonage number even though Vonage is bridging the call to your cell phone. More, the PBX may have trunks from multiple vendors and may use a different outbound vendor than the call arrives on, so you can't even reliably implement a rule that the outbound caller ID is rejected unless there's an active inbound call with the same caller id.
