Yeastar TA410 FXO Gateway with 4 Ports for PSTN and VoIP Integration

The Yeastar TA410 is a VoIP FXO gateway designed to connect analog PSTN telephone lines to VoIP infrastructure and IP-PBX systems for SMB organizations operating active analog lines and seeking to integrate them into IP telephony without replacing existing infrastructure. Four RJ11 FXO ports with SIP and IAX2 support enable bidirectional conversion between analog and VoIP networks in small-scale deployments. The device is used to reduce communication costs through SIP routing while preserving investment in existing PSTN lines.

The TA410 supports SIP (RFC3261) and IAX2, TLS and SRTP secure transport, voice codecs G.711 (alaw/ulaw), G.722, G.726, G.729A/B, GSM, and ADPCM, ITU-T G.168 LEC echo cancellation with Dynamic Jitter Buffer, VAD, CNG, and PLC. Fax is supported via T.30. FXO connectivity includes programmable AC impedance, hangup detection, answer detection, and Caller ID detection. Signalling covers FXO Loop Start and Kewl Start, with Caller ID in BELL202, ETSI (V23), and NTT (V23-Japan) formats.

The device integrates with a wide range of IP-PBX platforms and softswitches. Network features include DHCP, DDNS, OpenVPN, Static Route, and VLAN, with NAT Traversal via Static NAT and STUN. Management covers TR-069, auto provisioning, Web GUI, backup and restore, firmware upgrades via HTTP/TFTP, packet capture, and system logs. Security includes built-in Firewall, IP Blacklist, and Attack Alert. The compact 200×137×25 mm form factor with desktop and wall-mount options simplifies installation in space-constrained environments.

The TA410 is suited for SMB organizations with up to 4 active analog PSTN lines planning VoIP migration without abandoning existing lines, businesses adding analog trunking to IP-PBX platforms, offices where parallel operation of PSTN and IP telephony is an operational requirement, and deployments where compact dimensions and flexible desktop or wall-mount installation are determining factors.
