Engineering indicates that they are aware of performance problems when OVER
100 addresses are added to the Fax Phone Book. The recommendation is to limit
the number of addresses in the phone book to 100 or less. If more addresses
are added to the phone book the system may crash or hang.
The only workaround I can think of is to rename an existing phone book
which will automatically create a new one with the name "Fax Phone Book"
the next time the Fax option is used. A user could switch from phone book
to phone book by renaming the active phone book to something else and
renaming the phone book that is to be used to "Fax Phone Book." Not the
greatest solution but that's the only solution I can think of given the
current software.
