NAT Optimized SIP Media Path Without SDP
The NAT Optimized SIP Media Path Without SDP feature allows the creation of a shorter path for
Session Initiation Protocol (SIP) media channels by distributing endpoint IP addressing information with
Session Descriptor Protocol (SDP) of SIP messages. This feature allows endpoints to communicate
directly by using standard routing and eliminates the need for them to traverse through upstream NAT
routers.
