VoIP De-Mystified

How to SetUp & Connect VoIP Phones


If you are interested in how to compare and choose a VoIP (Voice over Internet Protocol) system, go to the VoIP for Dummies page.

Each provider of VoIP service will give you detailed instructions for connecting their system. You should follow those instructions. This page gives you some idea what is involved before you purchase a VoIP service. Although this information is generally correct, there may be variations for some VoIP services.


Basic Small Office VoIP Connection SetUp Info

Although most VoIP phones are IP phones that plug into a LAN, some VoIP services, especially those for residential use, allow you to use the same phone as you have used for POTS (Plain Old Telephone service), but instead of being connected to the phone line coming into your home or business, it's connected to a small box typically called a Digital Terminal Adapter (dta).

As with normal phone service, several phones may be connected to the line from the dta so that the phone number can be answered from different locations. The dta plugs into an ethernet port on a router connected to your LAN or broadband connection. Even if you do not have an available router port, many of the dtas supplied by VoIP providers contain two ethernet ports. To connect a dta with two ethernet ports, you can simply unplug the ethernet cable that currently plugs into your PC, plug this cable into one of the dta ethernet ports, and then run an ethernet cable between the other dta ethernet port and the PC ethernet port.

The setup in the previous paragraph works fine for many. However, if there is a lot of data traffic on your network, VoIP voice quality could suffer unless additional steps are taken. Data traffic includes video streaming, Email being sent or received, web surfing and ftping files. Again, understand that many use VoIP service with good quality while one or more PCs on the network are being used to surf the web or send and receive Email. However, there are cases especially in an office with many PCs where the VoIP service will suffer unless it is given prioriity over the data traffic. This is accomplished by activating what is called QoS - Quality of Service. To do this, you may need a more expensive router than you currently use. If your VoIP vendor provides a list of recommended routers, it's best to purchase one on that list because normally they recommend routers on which their service has been successfully tested.

Many of us use VoIP service without purchasing a special router. However, if there are a lot of PCs on your network working at the same time, or if just one PC often transmits and receives large files, you probably need QoS. Large files could be video files, Email attachments, large megabyte web pages or ftp transmission files. There is only so much capacity on your network. At times when most of the capacity is used by PC data, VoIP service will suffer.

Another consideration for many routers is that typically your router is set for DHCP which means IP addresses are assigned to PCs and dtas dynamically. Many networks and router default settings are such that the router assigns an IP address for a specified period of time called the lease time. The default typically is something like 99 days. For a PC, this is no big deal. A new lease can be obtained by rebooting the PC, for example. Well, dtas are not rebooted often. The time will come when the dta and/or the router will have to be rebooted unless the router is set so that there is no lease expiration. Contact your router manufacturer for info on how to do this.


More Advanced VoIP Info - QoS, MPLS, SDN WAN

If you have a large number of VoIP phones in your organization or if you want to be assured of consistent high quality voice service, you need to take steps to prevent your voice transmissions from being adversely affected not only in your LAN but also as the packets traverse the internet. The most common approach to assuring the priority of voice packets has been by using a MPLS network. More recently, SDN (Software Defined Network) services are being offered by numerous providers that are very efficient at providing a cost effective approach to maintaining high voice quality. In many organizations, MPLS networks are being replaced by SDN-WAN. Contact Persimmon Telecommunications for more info.
