Turn Off Message Alert For Missed Call Log? How To change time format to 12 hr?

[tima]

Hello,

There are two aspects on W52P I'm having trouble setting that are working on the T4X model phones.

1) Turn Off Message Alert For Missed Call Log. The voicemail indicator lamp on the cordless phones lights for missed calls and we would like to turn off this so that it only lights for voicemail.

2) Change the clock to a 12hr format on the handsets versus 24hr format.

Preferably both by provisioning server if not by GUI.

Thanks,

Tim
