CALLERID(rdnis)

Hi,

On my current SIP Origination provider, a call to ${CALLERID(rdnis)} returns blank every time - even when an incoming call is a forwarded call. The goal is to obtain the CID of the phone/device that is doing the actual forwarding. Does anyone out there have a SIP Origination provider that allows them to do this in Asterisk?

Please advise.

Thanks!
