Internet telephone systems, or VoIP (Voice-over-Internet Protocol), have four main components: handsets or other end-user devices, a call server or IP-PBX, gateways, and a data network. The handsets can either be existing traditional handsets that are connected to a regular PBX or they can be devices designed specifically for VoIP usage. Similarly, the call server or IP-PBX can be software on an existing server or a dedicated IP-PBX. VoIP gateways are used to connect the PBX to the data network. VoIP gateways convert analog voice signals to data packets that can be transmitted over the data network and then reassemble those packets at the other end, turning them back into analog voice signals.

What Advantages Do Internet Phone Systems Offer?
In recent years, great strides have been made in the quality of service, or QoS, as well as the set of features that VoIP systems offer. These improvements have removed many of the objections that many had to VoIP when it was first introduced. The case for VoIP is hard to ignore when you consider the return on your investment. VoIP systems use existing network infrastructure, thus reducing both management and maintenance costs. In addition, VoIP calls let you avoid the toll charges of telephone service providers. VoIP systems are quickly and easily scaled without massive incremental costs.

At Patton Electronics, we have developed a complete range of VoIP  equipment that has been used and proven successful in hundreds of successful installations worldwide. We have developed VoIP Gateways & Gateway-Routers and SIP handsets with features that match or exceed most traditional systems. Our range of routers and gateways can meet the requirements of any system, whether it be a SOHO installation, a hybrid system using existing legacy PBX and handsets, or a ToIP (Telephony-over-IP) system.
