Affordable, Clear, and Flexible Voice over IP

The Cisco SPA232D Multi-Line DECT ATA can enable small businesses, home offices, and residential environments to take advantage of high-quality, comprehensive voice over IP (VoIP) service using broadband Internet connections. On-premise mobile employees can remain in touch using support from its integrated Digital Equipment Cordless Telephony (DECT) base station.

Features and Capabilities

The Cisco SPA232D Multi-Line DECT ATA connects a standard analog telephone or fax machine to an IP-based data network. VoIP service providers can then offer business and residential users traditional and enhanced communication services using the subscriber's broadband connection to the Internet.

An inexpensive and easy-to-use solution that is installed by the end user, the Cisco SPA 232D Multi-Line DECT ATA is remotely provisioned, configured, and maintained by the service provider. Each SPA232D Multi-Line DECT ATA converts voice traffic into data packets for transmission over an IP network.

For Consumer and Business Use

Compact in design, the Cisco SPA232D can be used both in consumer and business VoIP service offerings, including full-featured hosted service environments. The Cisco SPA232D uses international standards for voice and data networking for reliable voice and fax operation.

The Cisco SPA232D Multi-Line DECT ATA also supports the new Cisco SPA302D DECT Handset , providing a reliable and cost-effective mobility solution for employees who must always be reachable, while typically on the move, whether at home or on-premise.

With the Cisco SPA232D, customers are able to protect and extend their investment in their existing analog telephones, conference speakerphones, and fax machines with an extremely affordable and reliable solution.
