Review Summary
With flexible configuration options, it has never been easier to deploy and expand a SIP-based phone system. The benefits of SIP are especially compelling in today's business environment, where every dollar counts. The reduced hardware costs and simplicity of routing calls over an Internet connection can add up to huge savings on monthly telephone bills. With the Panasonic TGP500B04 SIP phone system, it is quick and easy to add up to six cordless handsets-each with its own number. All that is needed is a single Internet connection and an electrical outlet near the location of the handset. Because it employs DECT technology, the connection is secure and the sound crystal-clear. Panasonic's SIP DECT phones use 100 percent recycled packaging materials and all new models are Energy Star qualified, which means they use about one-third less energy than non-qualified models.
