you'd be surprised how many people don't rule Invisibility hardcore like I do though, it's an easy thing to miss.
You can only disbelieve an illusion if the stat block states "Will disbelief" or if the spell text provides a specific mechanic.
From the 3E Main FAQ:
Older editions of the game listed the silence spell in the
Alteration school, but now silence is part of the Illusion
school. Does this mean that anyone in the area of effect can
try to disbelieve the spell, negating most of its effect for
enemy spellcasters?
No, if you could disbelieve a silence spell, its save listing
would be “Will disbelief.” Silence removes all noise in its area
and nobody gets a save against that. If the spell is actually
targeted on a creature or on a creature’s equipment, that
creature gets a Will save to negate the spell. If the save
succeeds, the spell fails and the area is not silenced.
Notice that Silence is also Illusion (Glamer).
As has been noted, the save for Invisibility is if someone casts it on you, and you don't want to be invisible. It's not a chance to disbelieve.
