The ZIP 4x4 integrates the functions of a managed switch with a business phone, and adds an address book, a calculator, and a speaker phone. The phone is referred to as a "four by four" because it has four call appearances and four Ethernet circuits. The phone is available in white and black.

The ZIP 4x4 is 100% based on open standards. It uses SSIP for call control, making it compatible with Windows Messenger and any IP phone system using the SIP standards. The switch on the phone supports all applicable standards for VLANs and QoS, ensuring it is compatible with any network, new or old. The phone can be powered from an ac adapter or receive power over an Ethernet connection.

By deploying the ZIP 4x4, an enterprise can achieve significant gains in productivity. In installation, only a single circuit needs to be taken to the desktop, to provide both voice and data communications. In deployment, by using open methods for configuration, an administrator can rapidly deploy the phones without any involvement by the end user. The phone makes moves and changes painless by requiring no re-provisioning and no rewiring.

In day to day operation, end users can access all features and functions quickly and unambiguously. The phone has 35 buttons and keys which eliminate the need to plow through menus and a frustrating quagmire of soft keys.
