Poly ATA 402 2FXS Voice Port VoIP Adapter with Open SIP and Power S...
Product Overview
The Poly ATA 402 is a two-port analog telephone adapter that connects legacy analog devices to a VoIP platform over open SIP. It provides two FXS voice ports and ships with a power supply, letting organizations keep fax machines, paging, or analog phones during a VoIP migration. It is a practical bridge between analog endpoints and modern SIP systems.
Product Description
The Poly ATA 402 lets integrators preserve existing analog equipment while moving voice to a SIP platform, supporting two analog devices from a single adapter. Its two FXS ports connect analog telephones, fax machines, or paging amplifiers to the network, and open SIP support means it interoperates with most hosted and on-premises platforms. The included power supply simplifies deployment. As an analog telephone adapter, it removes the need to replace working analog hardware immediately, reducing migration cost and disruption. It is centrally configurable alongside the rest of the voice estate. For sites with a couple of analog lines, the ATA 402 keeps them online economically.
