I have a BCM 400 running 3.7 software, and the customer frequently forwards their set to their cell phone, as they are frequently out of the office. The customer also has a PRI, coming out of a Siemens switch. Whenever the call (DID number) is forwarded, the CLID information that shows up on the cell phone is the OLI of the set, or the BTN for the PRI if the OLI is not programmed. Is there a way to display the CLID of the original caller (what shows up on the set if it is not forwarded), or this a CO issue? Thanks in advance for any help, as this is a HUGE issue to the customer.
