How to use VOIP phones

This page was last edited on 4 October 2020, at 05:54.

This document explains how to use VOIP phones. VOIP phones are phones that can be used like usual landline phones, but transmit all data over the internet, not over phone lines. In addition, it is popular to configure VOIP phones as part of a HostedPBX setup, in which case the phones become very flexible in what they can do.

1.2 How to use a PoE switch to power a PoE-supporting phone

A TP-Link PoE Switch

Some VOIP phones, for example the Cisco 504G, support receiving electricity over the network cable. This is called Power-over-Ethernet (PoE).

  1. You will need a device that passes the network signal and adds electricity to it. Routers that include PoE out of the box are rare, so you'd need either a single-port PoE adapter or a PoE switch. Ensure that the electrical output provided by the device is enough to power your phone. For example, this device is meant to power WiFi access points and was not enough for the phone. On the other hand, PoE switches should have no problem powering a phone.
  2. From your router, connect a network cable to Port #5 of the Switch.
  3. From any of the remaining ports in the Switch, connect a network cable to the phone. Connect to the port labeled "SW". Back of a Cisco VOIP Phone.jpg
  4. You can also connect the phone port labeled "PC" to any other device (typically a computer), and have the phone act as a mini switch that gives a network connection to your computer. Especially if your computer and phone are far away from the router or switch, this will save you the inconvenience of laying two long cables - one each for the phone and computer separately.

2 How to transfer calls between VOIP phones on the same hosted PBX system

0:01 Simple Transfer: Pick up call - Xfer button - Dial Extension - Xfer button

0:30 Talk with Staff before Transfer: Pick up call - Xfer button - Dial extension - Talk with the person - When done talking, press Xfer button

1:38 Parked Transfer: Pick up call - Xfer button - Dial 9000 - Anyone anywhere in the phone system can press 9001 to pick up that call

* Note that the 9001 becomes 9002 if 9001 is already taken (with another prior parked call), and 9003, and so on.
