A refurbished CP-7912G phone from Cisco just might be one of the very best purchases a small business can make if it wishes to acquire high quality VoIP technology. This phone is not the same as many of the conventional models available on the market. It is packed with additional features, which allow it to stand out. These phones have been developed to be perfect for a business environment. The availability of an an integrated Ethernet switch capable of providing LAN connectivity to a colocated PC would be one example of how this phone is perfect for the office. The look of the Cisco Unified IP phone 7912G is also highly stylized, which allows it to offer a visual appeal that is quite valuable.

The IP address assignment is DHCP. The lines supported are single lines. The Cisco 7912G phone works with Cisco CallManager 3.3(2) or later software.
