hepsim

Simulate varying phone calls by sending HEP for demos and statistics

Objective

Simulate a variety of calls to demonstrate use cases and statistics. It generates HEP and sends it based on defined callflows.

Current Caveats

• Only UDP
• Only simple Flow

Usage

Simply run after modifying config.json file.

HEP_ADDRESS=127.0.0.1 PORT=9060 node index.js

Utilize the example configuration for a view on how to use it.

The following callflows are available:

• default - Simple SIP call with media
• auth - Simple SIP call with auth challenge
• registration - Simple SIP registration
• auth_register - Simple SIP registration with auth challenge
• dtmf - Same as default but a DTMF signal (1) is sent before media flows
• timeout408 - A call based on default that receives a 408 as last response

Other scenarios can easily be added by modifying the sessionModule.callFlows object and adding respective functions in the simulationModule.update and hepModule functions.
