Mac-Address Table Issue

[bob.bartlett]

I have an environment with Cisco 7941 phones and Dell Notebooks with port replicators.  When i undock a notebook and plug it in elsewhere in the network the MAC-Address Table entry does not age out and consequently the notebook is unusable due to conflicting MAC-Address entry locations.  The only way i can get that MAC-Address out is to shut the port down and bring it back up.  My assumption is that the phone will not release the MAC-Address and therefore popultates the Table with that address and won't let it age out.  Any ideas???
