HP Poly ATA 402 VoIP Adapter

The HP Poly ATA 402 connects two analogue telephones or fax machines to a SIP-based voice network using dual FXS ports. It supports up to four SIP accounts, allowing each port to access any configured service independently. An integrated automatic attendant simplifies call routing for small office or home office deployments.

Network and power requirements

Verify that your network infrastructure provides Power over Ethernet or that a suitable mains outlet is available for the included power supply. Confirm that your SIP provider supports open SIP registration and can provision up to four accounts on a single device. Ensure the router or firewall allows the necessary SIP and RTP traffic for reliable call quality.

Ideal for small multi-line setups

This adapter suits users who need to operate two legacy handsets on a modern VoIP service with separate account credentials per port. It is not suited for installations requiring more than two analogue endpoints, for environments that demand proprietary phone system integration, or for buyers who need built-in wireless connectivity.

  • Two FXS ports let analogue phones connect independently
