Hi, I have a CICS 4.1 with a 4 Port Flash 2.0.10 installed at a business. The system has 5 lines to ring and appear on all 10 sets. AA is set to answer on 4 rings. Here lately the system will have a call coming in and will be picked up at the first ring by the system or voice mail and when someone tries to pick up on the line set states in use by extension 253. I have checked programming and there is not an extension 253. Any ideas? Thanks for any help.
