I always had the impression that 'nat=yes' is a bit of a legacy parameter that carries back to a time when SIP signaling was not assumed to be symmetrical, which was done later as a concession to the ubiquity of NAT. In other words, a SIP UA was not necessarily justified in concluding that the proper place to send a response to a client in dialogue was on the exact same UDP port that the SIP request originated from.
