INTRODUCTION

Product Overview

KS22 reimagines the familiar home phone as a dedicated communication product for children. Its retro-inspired tabletop design and physical dialing interface give children a recognizable way to reach family members without carrying or managing a general-purpose smartphone.

Designed for kids phone brands, family communication services and other B2B projects, KS22 can remain in a convenient place at home for predictable everyday calling. It offers businesses a distinctive hardware starting point for developing a child-focused communication service.
Technical Specifications

KS22 supports 2.4 GHz and 5 GHz WiFi connectivity using IEEE 802.11 b/g/n/ac/ax protocols. It uses SIP for voice communication and supports one SIP account, HD voice, Bluetooth 5.0 and a range of standard voice codecs and network protocols.

The device supports incoming and outgoing calls, speed dial, configurable ringtones, voicemail, app-based configuration and OTA upgrades. Contact settings and calling permissions can be adapted according to the customer’s platform and project requirements.

A Type-C port is provided for power input. The housing uses PC and ABS materials, and the product measures 135 × 230 × 125 mm.

CORE PRODUCT FEATURES

Simple Physical Dialing for Kids

KS22 replaces touchscreen menus with a physical dialing interface, allowing children to make calls without navigating apps, searching through menus or managing a smartphone. The tactile operation keeps the experience focused on voice communication and gives the phone a more memorable character than a conventional touchscreen device. It also helps brands position KS22 as a dedicated children's communication product rather than a simplified version of an adult smartphone.
Landline-Style Kids Phone

KS22 brings the familiar simplicity of a home landline into a WiFi-based phone for children. Designed to stay in one convenient place at home, it gives children a consistent way to reach family members without carrying a mobile phone. Unlike a traditional landline, KS22 connects through WiFi and does not require a telephone socket, SIM card or separate cellular plan. A compatible WiFi network, SIP account and service platform are required.
Parent-Managed Contacts and Calls

Parents or administrators can configure contacts and calling permissions through the management app. Approved contact control helps create a defined communication range around family members and other trusted contacts, while incoming and outgoing calling rules can be adapted according to the customer’s software, platform and service requirements. The child uses the physical phone, while contact management remains with the parent or service administrator.
Screenless and App-Free for Kids

KS22 is built around calling rather than digital entertainment. There is no screen, app store, browser, social media feed or gaming interface for the child to manage, so everyday use remains screenless and app-free even though parents or administrators can use the management app to configure the device. This separation provides straightforward calling for children while retaining the management functions required by adults and service providers.
WiFi SIP Calling Without a SIM Card

KS22 uses SIP for voice communication over 2.4 GHz and 5 GHz WiFi networks and requires neither a SIM card nor a traditional PSTN telephone line. Service providers can evaluate integration with their own SIP platform and build account-based, subscription-based or other calling plans around the final solution, giving them greater flexibility to develop a service model suited to their target market. SIP compatibility, account configuration and platform requirements can be tested during the sample stage.

Application

For Screenless Family Calling

KS22 gives children a dedicated home calling point for reaching parents and other approved family contacts without carrying a smartphone. Parents manage contacts and calling permissions, while children use only the physical phone and remain away from apps, browsing, games, social media and other unnecessary digital distractions.
