The SPA-1001 features one RJ-11 POTS (Plain Old Telephone Service) port for connection to existing analog phones, fax machines, PBX and key system communication platforms. The SPA-1001 includes an Ethernet interface for connection to a home or office LAN. The SPA-1001 can be provisioned via software controlled by the service provider or the end user.

Installed by the end user and remotely provisioned, configured and maintained by the service provider, each SPA-1001 converts voice traffic into data packets for transmission over an IP network. The SPA-1001 can be used in consumer and business IP telephony service offerings including full-featured IP Centrex. The SPA delivers clear sounding voice and reliable fax calling through its implementation of internationally recognized standards for voice and data networking.

Application Note:
The SPA-1001 supports the Sipura VSP feature. VSP stands for "Virtual Services Port." With VSP, users can configure the SPA-1001 to register with two independent VoIP services. Inbound calls can be alerted using a distinctive ring and outbound calls are supported using a configurable dialed access code, e.g. 9 or #. A conversation with a party on VoIP service #1 can be conferenced with a party on VoIP service #2 by simply using the three-way conferencing feature on the SPA-1001.
