BLF Key conflicts

[Attila]

Hello,

We T48G's keeps getting conflicts on the BLF Keys each day. When I reboot the devises the problem is gone and the BLF keys works properly on every devise. Then after a while (not even a day) some BLF's:

- show users "talking" when they are not? eventually after a while it goes to idle.
- doesn't show when users are "ringing or talking" at all while they are.
- cant puck up other phones with BLF while that phone is ringing (probably because of my second point)

This is starting to get a bit annoying. Can Someone plz direct us to a possible answer?
Or tell me what to supply.
