The working principle of peer-to-peer calls under different GKs is that when GK resolves that the called node belongs to the neighbor GK area according to the called number, GK supports requesting the neighbor GK to resolve the called number, neighbor After GK resolution is successful, the 1P address of the called node is returned to GK, and then GK returns the IP address of the called node to the calling node.
