The SpydurCore represents the bare essentials to running a successful telephone system. It uses the same primary software used across all three platforms (i.e. SpydurCore, SpydurByte, and SpydurPBX) and just plain works from the moment you plug it in, as there is no administration required. SpydurCore includes all telephony applications such as voicemail, automated attendant, and music on hold as standard. All that is required to get up and running are some telephones and either a.) an Internet Connection and SIP provider, or b.) a gateway with some analog lines.
Requiring less than 35 watts, the SpydurCore takes less energy than a standard lightbulb!
