    abstract =  {The NSIS NAT/FW NSLP provides traversal facilities for other application layer protocols. This document describes the interactions between SIP and NSIS signaling, to enable two NSIS aware SIP end applications to communicate normally through a network of NSIS Aware nodes, in a variety of NAT topologies.},
