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.
