VoIP-telefoonadapter Yeastar TA200

The VoIP telephone adapter Yeastar TA200 is a compact analog telephone adapter designed to convert traditional analog phones and fax machines to IP-based networks. Supporting voice codecs G.168, G.711, G.729A and G.729B and fax protocols T.31/T.38, the adapter enables clear voice transmission and reliable faxing over SIP networks. Certified for UDP, TCP, TLS and SRTP, the device is suitable for secure and interoperable operation with both Yeastar and non-Yeastar IP phone systems. With dimensions of 58mm x 85mm x 24mm and low power requirements (5V, 1A), the TA200 is intended for residential users and small businesses that need a cost-effective way to migrate existing analog equipment to VoIP.

Advantages

The TA200 provides high audio quality through multiple supported codecs and ensures compatibility with common fax standards, reducing the need for specialized equipment. Its small form factor and USB-power option make installation flexible and unobtrusive in limited-space environments. Web-based configuration simplifies setup and management, while support for secure transport protocols (TLS, SRTP) helps protect call signaling and media. Caller ID support enables standard call identification features for end users.

Suitable for

• Connecting analog telephones to an IP-PBX or SIP trunk
• Integrating fax machines into a VoIP network using T.31/T.38
• Small office and residential VoIP deployments
• Migrating legacy analog equipment to SIP-based telephony

Key specifications

• Supported voice codecs: G.168, G.711, G.729A, G.729B
• Fax protocols: T.31 / T.38
• Network protocols: UDP, TCP, TLS, SRTP
• Physical dimensions: 58 mm x 85 mm x 24 mm
• Power: 5V DC, 1A (can be powered via USB or IP-PBX where supported)
• Analog interfaces: single or dual FXS port options for analog devices
• Caller ID: supported

How to use

Physically connect the analog telephone or fax machine to the adapter's FXS port(s) and connect the adapter to your IP network via Ethernet. Supply power using a compatible 5V/1A USB source or a supported IP-PBX USB power output. Access the adapter's web-based administration interface through a browser by entering its IP address on the local network to configure SIP account details, codec preferences, and fax settings. After saving configuration and registering with the SIP server, test voice calls and fax transmissions to confirm interoperability and quality.

Recommendations

For best voice quality, prioritize G.711 where bandwidth allows and enable G.729 variants when conserving bandwidth. When using fax over IP, enable T.38 on both the adapter and the receiving gateway or PBX to minimize transmission errors. Place the adapter in a well-ventilated, indoor location near connected devices and use the web interface to keep firmware up to date and to configure TLS/SRTP for secure signaling and media.
