FEATURE VOIP
IP phones can be powered either
through a mains adapter or over the Ethernet network via POE switches. Standard PBX telephones are line- driven, so the system sends out the appropriate power voltage, but IP phones need their own power supply for backlighting the display, showing caller details and function key LEDs. If you are an installer, there are
immediate benefits of choosing the Power Over Ethernet route. It’s far easier to set-up because you don’t have to worry about installing mains cables. There’s also an advantage from an aesthetic point of view, with less cabling on desks and running throughout the building. This results in fewer electrical
dangers and associated health & safety issues. Power Over The Ethernet is the way forward. Another area for installers to be
aware of is that a VoIP network provides great opportunities for home workers. They can simply log on and become part of the network. Virtual Private Networks (or VPNs as they are known) are going to become even more crucial to the success of VoIP in boosting business efficiency. The more data we can send down the network, the more information a home worker can receive. They are fully integrated, as part of a very secure operating environment. It’s important for an installer to not just look at the staff in an office, but think about
those who have the capacity to work at home. This can bring significant benefits to a company’s productivity, as well as giving individual staff more flexibility and freedom to work away from their desks, while still having control and access of the applications and services available, just like a traditional office. Technology has come a long way
in a relatively short space of time, generating a host of sales opportunities for resellers and installers. But they need to tread carefully and fully understand their customers’ needs when developing the design and specification of an IP enabled network.
