3CX + Nutshell Integration with Kallio

Yes, 3CX and Nutshell integrate—technically. But "technically working" and "actually working well" are very different things.

If you're tired of context switching, missing features, or clunky workflows, Kallio provides the seamless integration experience you expected from the start. Direct connectivity, real-time sync, and zero friction.

Stop making workarounds work. Use an integration that actually works.

3CX

No Longer Maintained

The 3CX-Nutshell integration was built for an older version of 3CX and is no longer actively maintained. Users report version compatibility issues, template import errors, and licensing activation problems that require workarounds to resolve.

As both platforms continue to update, these compatibility problems will only get worse. For teams that need reliable long-term integration, an unmaintained connector is a liability.
