High-quality Voice and Fax over the Internet
Now you can use your phone over the Internet, without compromising on voice quality or phone and fax features. The Cisco SPA112 2-Port Adapter offers the benefits of high-quality voice over IP (VoIP) without the need to upgrade your existing analog phones.
Easy to install and use, the SPA112 works over an IP network to connect analog phones and fax machines to a VoIP service provider.
The Cisco SPA112 is compact in design and compatible with international voice and data standards. It can be used with residential, home-office, and small-business-VoIP service offerings, including full-featured hosted or open source IP PBX environments.
The Cisco SPA112 2 Port Adapter:
- Uses advanced voice quality-of-service (QoS) capabilities and the voice Session Initiation Protocol (SIP) stack
- Supports reliable faxing with simultaneous voice and data use
- Includes two standard telephone ports, each with an independent phone number, for use with analog fax or phone devices
- Is compatible with all industry voice and data standards and common telephone features such as caller ID, call waiting, and voicemail
