I have a CICS 6.0 4 lines in hunt, caller id works on all sets and lines, but caller id won't show on line 2 while on line 1 and so on, it will show the id of the call you are on at that time and will show if you place line 1 on hold as line 2 rings this is the case for all the lines. Have changed out the CI module with the same result. Will 7.1 fix this issue I have been told with mixed results.
