It accepts AC input voltage 100–240 V and includes power supply compatibility for typical office and home environments.

How to use

Connect the analog phone or fax to one of the FXS ports on the POLY ATA 402, plug the adapter into AC power, and configure SIP account settings using the device web interface or provisioning method provided by your SIP provider. Assign SIP credentials, set codec preferences (G.711alaw or OPUS as supported), and verify registration with the SIP server. After registration, place and receive calls through the IP network using the connected analog handset.

Usage recommendations

For reliable fax transmission, use the FXS port dedicated to fax and confirm T.38 or interworking settings with your SIP provider if available; choose G.711alaw for compatibility where OPUS is not supported. Ensure the adapter firmware is up to date and secure the device with strong admin credentials when connecting to public or business networks.
