Callerid from Cisco Callmanager

Total NOOB, have been setting up FreePBX to try to replace an aging Cisco Callmanager running os 4.1. So far I have created the SIP trunk to the current callmanager and can make inside/outside calls. One annoyance is when calls are forwarded from a DID on the Cisco box to FreePBX the caller id name is not showing. I am getting the caller id number. We currently have a PRI line that delivers caller id to the Cisco callmanager without problems. Any ideas on why the caller id name is not showing on FreePBX. Any help is much appreciated!
