KAER manufactures SIP and IP phones for business communication, hospitality, public service, and managed kids communication projects. The range includes entry-level Linux IP phones, Android SIP video phones, and screen-free Wi-Fi SIP phones for children.
Depending on the selected model and configuration, available functions may include:
• SIP voice and video calling
• Multiple SIP account registration
• IPv4 and IPv6 network support
• Ethernet, Wi-Fi, and Bluetooth connectivity
• PoE or DC power options
• HD voice codecs and noise control
• Android APK installation and video applications
• Web-based or device-side configuration
• Custom firmware, interfaces, and branding
IP Phone Options
The KS30 is an entry-level Linux SIP phone for offices, hotel rooms, reception desks, and customer service workstations. It supports two SIP accounts, Opus audio, dual 10/100 Mbps Ethernet ports, IPv4/IPv6, and optional PoE.
For projects that require touchscreen operation and video communication, KAER provides 8-inch and 10-inch Android SIP phones. Selected models support Wi-Fi 6, Gigabit Ethernet, PoE, cameras, APK installation, and SDK-based customization.
The KS21 and KS22 serve a different application. They are screen-free Wi-Fi SIP phones designed for controlled child-to-family calling. Both use Wi-Fi and SIP rather than a SIM card. Contact permissions and device settings can be managed by parents or service providers, while children use physical calling controls without installing apps on the phone.
Project Requirements
Before sample testing, confirm the SIP server or IP PBX, required SIP accounts, network environment, PoE standard, audio codecs, security protocols, Wi-Fi requirements, and target deployment scenario.
For Android models, confirm the Android version, required APK, GMS dependency, camera requirements, screen size, memory, and expected application workflow. Third-party application compatibility should be tested on the selected hardware and software configuration.

KAER supports telecom operators, system integrators, hospitality solution providers, distributors, and OEM brands with SIP configuration, firmware adaptation, UI customization, branding, packaging, and project integration.
