Shared phones, directory listing for line 2 user

My setup: AA50 appliance, Polycom IP 331 two line phones.

Our offices/phones are used at different times of the day by two different users. We have the problem that the second user (or line 2) on the phone is not listed in the directory, presumably because both users are on the same MAC address.

It appears that phoneprov’s pp_each_user function is where the “trimming” of the second user takes place.

Does anyone have any ideas of how to get the second user to be listed and make the change last through a reboot of the AA50? It is preferred that anything we do will not affect the operation of the GUI.
