The tutorial will be updated with details and screenshots if you contact us with specific request to extend it
To set up the GSM termination business you will need
  • GoIP gateway in destination country
  • Many SIMs for trials
  • Internet connection for the gateway
  • Time, energy to run the research

Configuring the StarTrinity softswitch

  • Register for free trial here - create account on our hosted softswitch, or use the softswitch on your server
  • Set up a Dbltek GoIP gateway at your destination, connect it to internet
  • Configure softswitch menu - SIM management - Gateway Locations
  • Configure softswitch menu - SIM management - Gateways
    • Add new gateway
    • Follow instructions, connect your GoIP gateway to the softswitch
    • If the gateway is still offline, troubleshoot your internet connection using GoIP - Tools - Ping, make sure that WAN settings are correct
    • Try to access the GoIP gateway via our switch IP
    • Click softswitch menu - SIM management - gateway details - auto configure gateway
  • Insert few SIM cards, see their status in softswitch - SIMs. The status should be "online"

    • Add originator for your test softphone (e.g. Zoiper). Set user name and password in the softswitch, enter same username/password in the softphone
  • Make test call from the softphone or directly from softswitch Web UI (originator details - make test call)

Running research of SIM blocking

  • Write down and send to us all info about manipulation with the SIM cards for analysis (e.g location, activation, deactivation, recharging/top-up, etc)
  • Test with manually generated traffic
  • Test with automatically generated traffic
  • Test with cleanest traffic
    • Try various sources of traffic
    • Ask us for clean traffic, we will ask our partners
  • Give us access to the softswitch to analyse the test results
  • Ask us to optimize the configuration of the softswitch to protect the SIM cards based on your research. Perform the testing and re-configuration multiple times
