This is a collection of tools used for adding interconnect and billing to VBTS. It's based on tools developed for the Papua VBTS network, a project of UC Berkeley TIER. You can read our paper about the network here.
This project includes:
- vbts-twilio: A (misnamed) implementation of interconnection that support send and receive of SMS through both Nexmo and Twilio.
- vbts-credit: A prepaid billing and credit transfer system.
- vbts-configs: Basic Freeswitch dialplan and chatplan that allow you to integrate with libvbts, vbts-twilio, and vbts-credit.
You should first go through the OpenBTS installation procedure, and set up Freeswitch too. Make sure you build and install mod_xml_cdr when you're setting up Freeswitch.
Set up the dependencies:
- Install the following Python packages using pip: snowflake, requests, webpy, smspdu, twilio, phonenumbers, flup.
- Instal pylibnexmo.
- Install lighttpd, and configure it to run on port 8081.
After that, just install vbts-credit and vbts-twilio as you normally do Python packages.
cd vbts-credit
python setup.py install
cd ../vbts-twilio
python setup.py installYou can then develop your own Freeswitch diaplan/chatplan based on the sample ones provided in vbts-configs.
There are a lot of potential hangups in all this: building your own mini-phone network isn't simple. We're working on making the process easier, so please let us know if you run into trouble.
