RedFS - FreeSWITCH Event Socket
FreeSWITCH Event Socket Protocol Client Library by Python3:Gevent
It's origin fork from greenswitch, with additional implementation:
- Minimalize dependency (gevent only)
- Large scale adaptation
- Bug fix
- Dualstack IPv4/IPv6
- Python3 syntax improvement
Installation
pip3 install redfs
