Technical Committee – VoIP/Packet

The Voice over Internet Protocol (VoIP)/Packet Committee’s   goal is to identify and solve technical issues relating to call delivery from VoIP sources and migrate existing 9-1-1 technologies into a packet environment for both voice and data.  Identified technical issues are handled via Working Groups that are formed to accomplish specific goals, which usually result in some type of official NENA documentation.
