on Phone talk If caller need someone who is not here, I would say"sorry she is not available now, please call later". Does that okay? or Should it be"she is unavailable now"?

pls help me in "she just got off from work today" I want to express"she just got off from work today" simply, but do not know how. finish her work today？or she called it a day today? thx!Thank you! Brigitte
