node-red-contrib-hep

Node-RED function that takes the msg.payload and encapsulates or decapsulates it to HEPv3.

Installation

Either use the Manage Palette option in the Node-RED Editor menu, or run the following command in your Node-RED user directory - typically ~/.node-red

    npm i node-red-contrib-hep

Usage

If the input is a buffer it tries to parse it as hep and creates a javascript object. If the input is a javascript object w/ HEP rcinfo and payload, it will create a HEPv3 buffer.

Example: payload

ACK sip:883510000000091@domain.net SIP/2.0
Via: SIP/2.0/UDP 192.168.1.23:5060;rport;branch=z9hG4bK484759904
