Yeastar TA400 4 FXS VoIP Gateway

Technical Specifications of Yeastar TA400

The Yeastar TA400 FXS VoIP gateway connects analog telephones, fax machines, door phones and legacy PBX extensions to any SIP-based IP PBX or cloud phone system. Every FXS port delivers dial tone, ring voltage and caller ID to an ordinary analog device, so a hotel, clinic or factory can move to VoIP without replacing hundreds of handsets.

Key Features of Yeastar TA400

Keep your analog handsets

Each FXS port powers a standard analog phone or fax with ring voltage, caller ID and message-waiting indication — the user notices nothing except better call quality.

Works with any SIP platform

Registers to Yeastar P-Series and S-Series PBX, 3CX, Asterisk, FreePBX, Microsoft Teams SIP gateways and every major cloud provider; IAX2 is supported for legacy setups.

Reliable fax over IP

T.38 real-time fax and G.711 pass-through keep multifunction printers and fax lines working after the migration to VoIP.

Set-and-forget provisioning

Auto-provisioning from Yeastar PBX, bulk configuration via the web GUI, SNMP monitoring and encrypted TLS/SRTP signalling for secure sites.

Zero-touch failover

Configurable dial plans, call routing and SIP trunk failover mean phones keep ringing even when a trunk or WAN link drops.

Why Choose the Yeastar TA400

Yeastar gateways are the most widely deployed VoIP gateways in the GCC because they simply work with every PBX. The Yeastar TA400 gives you 4 FXS ports in a desktop unit, a web interface an IT generalist can configure in an afternoon, and firmware that Yeastar still updates. For a business in Dubai the practical benefit is a migration to VoIP that costs a fraction of replacing every phone or renegotiating carrier contracts.

Who Is the Yeastar TA400 Built For

The Yeastar TA400 suits hotels converting room phones to VoIP one floor at a time, hospitals and clinics with nurse-station and fax lines, schools, factories with intercoms and analog paging, and offices keeping a few analog devices during a PBX upgrade. IRIX supplies it to system integrators and directly to corporate IT teams across the UAE, with export to CIS and Africa.

Hands-On Review and Customer Feedback

In our deployments the Yeastar TA400 registers to Yeastar P-Series and 3CX within minutes, and the auto-provisioning template removes most manual work. Call quality on G.711 is indistinguishable from the analog line it replaces; fax reliability depends on enabling T.38 on both ends, which we configure for customers on request. The unit runs cool and has proven stable across multi-year installations in hotels and clinics.
