Do Buddhists think other religions are wrong?

I appreciate that religion can be many things but I want to consider the more soteriological aspects of religion. If we can take as a premise that religions including Buddhism have a strong concern about salvation - this would mean that Buddhism and other religions have competing views on this matter. Do Buddhist texts and Buddhist teachers think that other religions are wholly wrong in this regard or maybe partially right or even perhaps everyone is correct in some sense? I'm particularly interested in references for reasonable authoritative texts or quotes from teachers either ancient or contemporary. Also are certain schools of Buddhism more open to other religious views and perhaps other ones more exclusive in their views?
