Call History Logs... Incoming, outgoing, missed, all, etc.
Initially the 5240 call history was fine. We did a set type change (ML Set Assignment form) to make it a 5235 and then swapped out the 5240 set for a 5235.
Initially the 5235 call history logs were fine, although seems we did notice it needing to be "refreshed" in order to display most recent history logs. That seemed quite odd. Shouldn't call history accumulate dynamically and display as soon as you call up the history screen without having to be manually polled with the refresh softkey? Alas new calls were not displaying in history until pressing the refresh softkey.
Long story short, the cust ended up not liking the 5235 (complained about screen glare and touchscreen functions too small) so we swapped him back, changing the 5235 set type back to 5240 and giving the cust his original 5240 back. Now the call history logs in the 5240 were completely dead. No call history at all. Next trip we swapped this 5240 with another (brand new) one, same symptoms. No history.
Next we changed the 5240 set type back to 5235 and reconnected the 5235. However this time the 5235 call history logs were dead too. The 5235 worked ok just no call history logs, at all, period.
To fix, we finally ended up completely deleting the user (totally). Then we programmed up a new 5240 on a different unused number and tried that. This worked and we had call history logs working again. Finally we renumbered the newly programmed set back to the original user's number and this too worked. The user is completely back in business tho he lost all his personal speed dial nbrs, personal directory info, etc. All that he had to reenter from scratch.
No other users call history was affected. Only the set we tried to swap back & forth from 5240 to 5235 then back to 5240.
