• The phone system runs entirely in the cloud; no on-site hardware is required.

• Users can make calls with a single number from various devices (PC, smartphone).

• Features such as voicemail, call queues, and CRM integration are included.

• Communication is flexible, location-independent, and secure with EU data hosting.

• Setup is quick and easy, with porting of existing phone numbers.

• NFON replaces traditional phone systems with a modern, cloud-based solution for flexible business communication.

With NFON you eliminate the telephone system hardware, the telephone connection and the maintainer. The system is also flexible, scalable and simple to administer.

The base technology is called hosted PBX, often called IP Centrex. Both refer to the same concept: the telephone system is not installed at the company site but at an external data center, and can be accessed anywhere using the Internet.

The telephone system is operated over the Internet. The system itself is located at the NFON data center – it has a resilient set up failover at geographically separated servers. All services are guaranteed.

Absolutely! We optimized our platform for your colleagues all over the world. Not matter if you’re part of a call center, work in retail or e-commerce. We offer you a custom system.

In the Cloudya app, you can connect a call by following these steps:

1. When you are in a call and want to connect it, you can first put the call on hold by clicking the Hold button.

2. You can then accept or make a second call.

3. To connect the call, transfer it by selecting the desired contact or extension and confirming the transfer.

4. Successful transfer is displayed at the bottom of the screen with the message Call transferred to [person's name].

These functions are available in both the Cloudya Desktop app and the Web app.

For cloud telephony with NFON, you need:

• A stable internet connection with at least 100 kbit/s per simultaneous call and low latency (<100 ms).

• End devices such as PCs, laptops, smartphones, or IP phones; Cloudya also works without special hardware, e.g., via app or browser.

• A firewall configuration that allows VoIP traffic (SIP, RTP).

• Supported operating systems and browsers (e.g., Windows, macOS, Android, iOS, current browsers).

• A microphone and camera for voice and video functions.

• The platform is device-independent and enables flexible use without complex hardware.

The difference between SIP and VoIP is:

VoIP (Voice over IP) is the technology that transmits voice over the internet, i.e., the method by which phone calls are made digitally over IP networks.

SIP (Session Initiation Protocol) is a protocol that controls communication: It initiates, manages, and terminates phone or multimedia sessions. SIP is therefore a kind of "rules set" that enables VoIP calls and can also control video, messaging, and more.

In short: VoIP describes the "what" (voice transmission over IP), SIP the "how" (the protocol for controlling communication).

Yes, the NFON Cloud PBX is very well suited for small businesses. Key reasons:

• It's flexible and scalable, adapting to your company's growth.

• No expensive on-premises hardware is needed, as the phone system runs entirely in the cloud.

• Easy setup and management, even without IT experts.

A PBX (Private Branch Exchange) is a telephone system that manages internal and external telephone connections within a company. At NFON, the PBX is cloud-based ("Cloud PBX"), meaning the telephone system runs entirely in the cloud without any local hardware.

Unified Communications (UC) refers to an integrated solution that combines different communication methods and channels into a single platform to improve collaboration and information exchange.

The advantages of Unified Communications at NFON summarized:

• Increased productivity through seamless collaboration

• Cost savings thanks to cloud-based solutions without expensive hardware

• Location-independent communication and mobile working

• Integration of various channels such as telephony, chat, video, and collaboration

• Support for modern, flexible work models

• These advantages make companies more efficient, flexible, and future-proof.

UCaaS (Unified Communications as a Service) is a cloud-based communications solution that combines telephony, video meetings, chat, and collaboration in a single platform. It is offered on a subscription basis, meaning companies pay monthly or annually per user. The provider handles the infrastructure, updates, and maintenance. This ensures the system remains scalable, flexible, and accessible from anywhere.

With NFON, you can make calls using the following apps:

Cloudya Web App: Make calls directly in your browser with features like click-to-dial, caller ID, and device selection (e.g., app, desk phone, mobile phone).

Cloudya Desktop App: Make calls via the desktop application with comprehensive features such as call forwarding, a favorites list, CRM integration, and click-to-dial.

Cloudya Mobile App (iOS and Android): Make calls on the go using VoIP with WiFi or mobile data, including call options like mute and speakerphone.

An NFON softphone is software that allows you to make calls via the internet (VoIP) using a PC or mobile device. A telephone is a physical device that connects directly to the telephone system. The softphone offers greater flexibility, mobility, and advanced features, while the telephone serves as a traditional hardware device.

The cloud is a network of distributed data centers that provide storage, computing power, and software. Instead of running programs locally on a personal computer or server, users utilize resources provided via the internet.

API integration with NFON means you can integrate your NFON cloud-based phone system into your own systems via Application Programming Interfaces (API). This allows you to manage extensions, control calls, and automatically retrieve and process user information. NFON offers various APIs for this purpose, such as the Portal API for administration and the CTI API for telephony integration.

These open, flexible APIs enable customized solutions and automations that make your business processes more efficient.

You can integrate your NFON cloud phone system into Microsoft Teams in two ways:

Cloudya App for Microsoft Teams

• Installable directly from the Teams App Store

• Enables telephony and all Cloudya features in Teams without additional licenses

• Ideal for simple and immediate integration

Premium Integration via Direct Routing

• Connects Teams and the NFON phone system via Direct Routing

• Offers advanced features such as call queues, ACD routing, and contact center integration

• Setup via the Microsoft Teams Admin Center

• Requires a suitable Microsoft Teams license

Both options enable professional and flexible telephony in Microsoft Teams.

NFON primarily offers the following integration types for cloud-based phone systems:

• RESTful APIs (e.g., Service Portal API) for administration and automation

• CTI API for phone control and real-time call events

• Event-based integration (similar to webhooks) via CTI API for real-time events

• SDKs (proprietary, e.g., with nCTI Premium) for advanced call integration

These APIs typically use JSON and HMAC authentication and allow for flexible integration into your own systems.
