Companies spend billions of dollars each year on internal phone calls and faxes between their own offices. Cisco Systems now offers companies a way to significantly reduce these costs without compromising voice and fax quality, and without impacting the way employees make phone calls or send faxes.Cisco is now announcing new voice/fax network modules for the Cisco 3600 multifunction platform. This announcement marks the first step in adding multiservice (integrated voice, data, and video) functionality to its popular Cisco 3600 series. The new Cisco 3600 offers unparalleled multifunctional capabilities in a midrange solution, with strength in traditional LAN-to-LAN routing, dial access, legacy, and now, multiservice applications. No other networking vendor comes close to offering this breadth of functionality in one midrange device.This is a two voice/fax interface card slot network module.
