M3904 display issue

[mindamartine]

Here is the scenario.
Yesterday our Option 81C lost power. Everything came back up, but today we are noticing an issue.

We have M3904 phones. Everyone has add-on modules and they have SCN keys with everyone's extensions on them.
What is happening now that did not happen before is:
When a number is called, example DID number xxx-4743, and that person answers it (KEY 0 Marp person) it continues to show the number that called in the display of everyone else's phone even though the call was answered.
This happens on all phones, not just xxx-4743.
Any ideas?

Can you print out a few of the affected phones and copy/paste here? Also provide other information such as software version, patches, etc... (LD 22 - PRT - ISS, LD 143 - MDP ISSP), etc...
