sundance-communications.com Forums Telephony Discussion Phone & VoIP Systems Mitel Telephones & Systems ring groups and clid

Having issues with a 3300. It is using release 6.0 SP3.
The customer is using a mix of 5220s,5215s,and 5215s in his ring groups.
When outside calls come into the ring groups the CLID is incorrect.
When outside calls are transferred from the Auto-Attendant or the Operator the CLID is correct?
Any Ideas.
