Product information

Description

HP POLY ATA 400 1FXS is a compact VoIP adapter designed to convert an existing analog telephone or fax device into an IP phone using Open SIP (SIPv2). The unit provides a single FXS voice port and supports the G.711 alaw and OPUS codecs for voice transmission. It is compliant with FCC part 15 Class B and CE standards and accepts DC power via an AC input of 100–240 V at 50/60 Hz. With dimensions of 88 × 88 × 26 mm and a weight of 0.065 kg, the adapter is sized for small office and home deployments where preserving existing analog handsets and simple SIP integration are priorities.

Advantages

The HP POLY ATA 400 1FXS enables cost-effective migration to VoIP by reusing analog phones and fax machines without replacement. Its support for Open SIP and SIPv2 ensures interoperability with a wide range of SIP providers and PBX systems. The inclusion of the G.711 alaw and OPUS codecs allows for flexible voice quality and bandwidth optimization. Compact dimensions and low weight make installation unobtrusive, and compliance with FCC and CE standards meets regulatory requirements for consumer and small business environments.

Suitable for

  • Converting single analog telephones to SIP in small offices
  • Integrating fax machines into a SIP-based network
  • Home office VoIP setups where preserving existing handsets is preferred
  • Environments requiring a small, low-profile adapter for SIP access

Key specifications

  • Voice interface: 1 FXS port for analog telephone/fax connection
  • Supported protocols: Open SIP, SIPv2
  • Audio codecs: G.711 alaw, OPUS
  • Power input: AC 100–240 V, 50/60 Hz (DC power supported via adapter)
  • Regulatory compliance: FCC part 15 Class B, CE
  • Dimensions: 88 × 88 × 26 mm
  • Weight: 0.065 kg

How to use

Connect the analog phone or fax device to the device's FXS port, then connect the adapter to power using the supplied DC/AC power adapter rated for 100–240 V at 50/60 Hz. Configure the adapter with your SIP account credentials (server address, username, and password) using the device’s web interface or provisioning method supported by your SIP provider. Select an appropriate codec (G.711 alaw or OPUS) based on desired voice quality and available network bandwidth. Verify registration with the SIP server and perform test calls and fax transmissions to confirm proper operation.

Usage recommendations

Place the adapter near the analog device and a reliable internet connection point. For best voice quality, use OPUS where bandwidth and network conditions allow; use G.711 alaw for compatibility with legacy SIP services. Ensure firmware is kept up to date and follow your SIP provider’s provisioning guidelines to maintain security and service reliability.
