GOnnect is a desktop VoIP client designed for managed communications environments. Rather than providing a conventional account setup wizard, it is intended to be provisioned with a configuration file containing the information needed to connect to a SIP service.
The application integrates telephone functionality with desktop contacts, calendars and communication hardware. This makes it particularly suitable for organisations where employees use SIP extensions alongside corporate directories, shared calendars and compatible headsets.
GOnnect also integrates Jitsi Meet, allowing users to move from a telephone conversation into a video meeting. Its modular architecture provides additional ways to connect messaging services and external information sources without turning the main application into a general-purpose collaboration suite.
Configuration templates are available for several telephone services, helping administrators prepare working installations without creating every setting manually.
This is free and open source software.
