3CX Mobile Applications
Stay connected wherever you go with the 3CX mobile apps, available for both iOS and Android devices.

Desk Phones
For those who prefer a traditional setup, 3CX supports a wide range of IP desk phones. These phones are pre-configured, making setup straightforward. They offer a dedicated device for your business calls, ensuring a reliable and professional communication experience. Even with desk phones, you benefit from the advanced features of the 3CX system.
Advanced Features and Customisation
While the basics are easy to grasp, 3CX offers a wealth of advanced features that can significantly enhance your business's productivity and customer service. As you become more comfortable, explore these powerful tools:
Call Queues and Ring Groups
For businesses with customer-facing teams, call queues and ring groups are invaluable. Call queues manage incoming calls, distributing them to available agents based on predefined rules, ensuring no customer is left waiting. Ring groups allow multiple phones to ring simultaneously or sequentially when a call comes in, guaranteeing a prompt response.
Voicemail to Email
Never miss an important message again. 3CX can transcribe your voicemails and send them directly to your email inbox as an audio file and text. This allows you to manage your messages efficiently, even when you're away from your desk.
Reporting and Analytics
Gain insights into your team's performance and customer interactions with 3CX's comprehensive reporting tools. Track call volumes, answer times, call durations, and more to identify areas for improvement and optimise your communication strategy. Key reports include:
| Report Type | Description | Key Metrics |

Popular CRM integrations include Salesforce, HubSpot, and Zoho.
Auto Attendant (IVR)
Automate your call handling with the Interactive Voice Response (IVR) system.
