that is the only way. you can't set individual numbers to ringtones, only groups. theoretically, you can have up to 11 ringtones. you have 10 groups ringers and then a standard ringtone for numbers that are not in the 10 groups. even with 300 numbers, i haven't used all 10 groups yet. you must have a lot of numbers or breaking down your call groups too specifically. i broke my numbers down to family, friends, business, etc.

I was wondering if there was any other way to set specific rings to certain numbers. right now, i've been placing numbers in groups and assigning rings to each group. the problem with this is that i can't assign more than 10 different ringtones.
