EZ-ISDN 1 (if you do not want Voice Mail) or Package V or EZ-ISDN 1A (if you want
Voice Mail).
If you make this change, however, you should be aware that certain constraints
apply to both U/EZ-ISDN 1 and V/EZ-ISDN 1A -- in particular, that these codes do
not provide support for simultaneous voice and data on the same Directory
Number. For a full explanation of these constraints, refer to the section, “What
Are the Supplementary Voice Services Included in U/EZ-ISDN 1 and V/EZ-ISDN
1A?” If you must have simultaneous voice and data on the same Directory
Number, refer to the section, “What If I Need Simultaneous Voice and Data
Capability on Both Numbers?”
