--- | ---
The maximum number of callers in a single conference (maximum of 8) has been reached. Maximum number of conferences that the system can support has been reached. If COS option Call-Waiting Swap is enabled, user cannot make conference call from single line set. This is because Call-Waiting Swap overrides the conference feature. Incorrect Calling Line Identification (CLID) is being sent to third party. | Refer to the Conference feature in the System Administration Tool online help for the conference limitations for the 3300 ICP controller. Disable Call-Waiting Swap in the COS. Enable “Replace External CLID” in ISDN Protocol form of trunk.
