The Yeastar TA3200 is an analogue VoIP gateway that connects legacy telephones, fax machines, and conventional telephone systems with IP-based telephone networks. It serves as an interface between analogue end devices and IP telephone systems, enabling existing analogue infrastructure to be integrated into a modern IP telephony system. The device is particularly suitable for small and medium-sized enterprises that wish to carry out a step-by-step migration from analogue to IP-based communication systems. It supports the SIP protocol family (RFC3261) as well as IAX2, enabling connection with a wide range of IP telephone systems and VoIP platforms.
Applications
The TA3200 is used to connect analogue extensions such as telephones or fax machines to IP telephone systems. It extends existing IP systems with analogue connection options, allowing companies to continue using existing devices without switching to IP technology. Integration is achieved via 32 analogue FXS interfaces, which are implemented using RJ11 connectors. Additionally, the device features two RJ21 ports, which can be used to connect multiple analogue end devices via a common connector.
Functions and Equipment in Detail
The gateway offers a web-based graphical user interface, simplifying configuration and management of the device. It supports flexible call rules, including call forwarding when absent, busy, or always, as well as functions such as Do Not Disturb (DND), call parking, paging (radio call), and a block list. Call number transmission is supported via various standards, including BELL202, ETSI (V23), NTT (V23-Japan), and DTMF-based. Connection termination methods include busy tone and polarity reversal. Device management is performed via protocols such as SNMP, RADIUS, and TR-069, with remote management support.
Technology Explained Simply
The TA3200 uses SIP (Session Initiation Protocol) according to RFC3261 as its primary communication protocol to initiate and control calls over IP networks. It supports various transport protocols such as UDP, TCP, TLS, and SRTP, ensuring secure and reliable connections. Voice transmission is carried out using various codecs, including G.711 (alaw/ulaw), G.722, G.723, G.726, G.729A, GSM, and ADPCM, achieving high voice quality and efficient bandwidth usage. Echo suppression follows ITU-T G.168 LEC, ensuring clear voice transmission. A dynamic jitter buffer and PLC (Packet Loss Concealment) ensure stable connections even with network fluctuations. Fax transmission is handled via T.38 and pass-through, ensuring reliable fax functionality over IP networks.
Compatibility and Accessories
The gateway is interoperable with systems such as Asterisk, Lync Server, and FreePBX. Additionally, it is certified for Elastix and BroadSoft, facilitating integration into existing IP telephony infrastructures. It supports SIP servers and SIP trunks, as well as SIP peer mode. Network configuration is performed via DHCP, static IP addresses, DDNS, OpenVPN, PPPoE, and VLAN. QoS functions such as DiffServ, ToS, and 802.1P/Q enable prioritization of voice data in the network. NAT traversal is supported via static NAT and STUN, enabling use in networks with NAT functionality.
Mounting and Installation
The device can be mounted either on a desk (desktop) or on a wall (wall-mount). The TA3200 version is also suitable for use in a 48,3 cm ( 19 inch ) rack, enabling integration into server or network enclosures. Power supply is via 12V, 5A, with the device connecting to an AC voltage of 100–240V. Dimensions are 440 mm (L) × 250 mm (W) × 44 mm (H). The device is designed for operation at temperatures from 0°C to 40°C and humidity levels from 10–90 % (non-condensing).
Operational Advantages
The web-based configuration makes setup and maintenance of the gateway simple and quick. Support for numerous codecs and protocols ensures high flexibility when integrating into existing systems. The fax function via T.38 ensures reliable transmission even over IP networks. Support for remote management and various network protocols enables central management and secure network integration. The high number of 32 analogue channels makes the TA3200 particularly suitable for companies with extensive analogue end devices.
