release node
The initial destination of a call from a pivot node.
Note: A service or network capability provided at the release node, after determining the call should be connected to a destination node other than itself, may invoke RTP (registration request protocol) to have the new connection established from a pivot node earlier in the call path. After releasing the call to a pivot node, the release node no longer participates in the call. The release node must be a SS7 Signaling Point. [T1.661-1997]
