Product information

Description

POLY ATA 402 is a compact 2FXS voice port VoIP adapter that converts existing analog phones into IP phones using Open SIP and SIPv2. It supports G.711 (alaw) and OPUS codecs and enables VoIP access without requiring an Ethernet connection or Wi‑Fi, allowing you to keep legacy handsets while integrating them into an IP telephony environment. The device accepts DC power and includes an AC power supply compatible with 100–240 V, 50/60 Hz. Its small footprint makes it suitable for home offices and small business deployments.

Advantages

The adapter provides a sustainable and cost‑effective way to migrate to VoIP by reusing existing analog phones and simplifying faxing and management. Support for Open SIP ensures interoperability with standard VoIP platforms, while G.711 and OPUS codecs deliver compatible voice quality across networks. Compact dimensions and included power supply allow easy installation in limited spaces.

Suitable for

  • Converting analog desk phones to IP for small offices
  • Home VoIP setups where existing handsets are retained
  • Fax over IP and mixed analog/IP telephony environments

Key specifications

  • Ports: 2 FXS voice ports for analog phone connection
  • Protocols: Open SIP, SIPv2
  • Voice codecs: G.711 (alaw), OPUS
  • Power: DC powered with included AC adapter (100–240 V, 50/60 Hz)
  • Dimensions: 96 × 96 × 22 mm

How to use

Connect an analog phone to one of the FXS ports and link the adapter to your IP service according to your provider's SIP settings. Attach the supplied AC power adapter to power the unit. Configure SIP account parameters (server, username, password, transport) using the device's web interface or provisioning method recommended by your VoIP provider. Verify codec preferences and any fax passthrough settings as required.

Usage recommendations

For reliable operation, use with a compatible SIP service or PBX and confirm codec support (G.711 or OPUS) on the server side. Place the adapter where it has easy access to analog handsets and the network provisioning device; avoid exposing the unit to extreme temperatures or moisture.
