What is the proper estivation temp?

We had a bad cold snap in september and we couldn't afford propane at the time, so it got pretty darn cold in here, that's pretty much when he stopped eating and went into estivation.

Right now he's in ecoearth, but it's dried out now. Our house temp is about 69 degrees.

He last ate in late august. We had been feeding him dusted crickets and mealworms every couple of days.

When we first got him he peeped a lot, but then stopped peeping a month after he'd been with us.

Could I just pull him out of hibernation and keep him active? Or does he have to go into estivation or he won't survive? I have a res that I never hibernate because I don't plan on breeding him, so he has "optional" torpor. Is it the same with these toads?

Thanks.
