The 5 Most Important Aspects of VoIP Business Phone System Preparation

VoIP Business Phone System preparationVoice over Internet Protocol (VoIP) has innumerable benefits, but there are a few accompanying challenges. The good news is that these challenges aren’t difficult to overcome if you prepare accordingly. We’ve listed the six most important aspects of VoIP Business Phone System preparation below.


The first thing you should determine is what kind of calls you need to make. There are a couple of different ways to make a VoIP call; from a desk phone, from a computer, or from your smartphone. Prior to making any networking decisions, you need to figure out how you are going to make calls.


Another important VoIP Business Phone System preparation is to get the correct Ethernet cables. Cat 6 cables are one of the better choices, but they may prove too costly for smaller businesses. Cat 5e cables are a more budget friendly option, and should work fine for most businesses. However, potential VoIP users should avoid older Cat 3 cables, as their capacity and compatibility is not a good fit for VoIP.

Power Supply

Next, you need to ensure that you have the appropriate power supply. Power over Ethernet (PoE) cables are the best option; they allow devices not plugged into an AC source the ability to draw power from your internet.


Like many things on this list, you need to determine if your router is able to handle the new traffic from VoIP. If your router doesn’t have Packet Per Second (PPS) capability, you should upgrade it. PPS capability provides traffic shaping and allows you to prioritize voice and video data on your network.


Software-defined firewalls are vital to VoIP Business Phone System preparation. Software-defined firewalls are designed to filter internal data traffic and packets as opposed to only data traffic.

These tips should aide you in making the proper decisions regarding your new VoIP system. If you have any questions regarding VoIP or business phone systems in general, please contact Advanced Communication Systems today at 800-750-3624. You can also follow us on Facebook.

How Data Networks Impact Your Office Phone System

behindrack_houston_txIn today’s world, all Office Phone Systems utilize VoIP to a certain degree. SIP Trunking, for example, is entirely VoIP.  Analog systems aren’t one hundred percent VoIP, but most use VoIP for their data network.

Complete VoIP networks are actually made up of two networks; a local area network (LAN) and the Internet connection (wide area network or WAN).  From the desktop to the Internet your network will need to support voice. While voice may just be a different type of data traffic, it is vital to your office phone system. If it lags, your phone call quality will be poor. There are a few different types of data networks:

Routers – In most cases your carrier will install your Internet router. Routers pass voice transmissions without much of an issue usually. However, some carriers (and circuit types) require small tweaks made by the carrier to correctly support voice.

Firewalls – Implementing a modern telephone system with a firewall can be tricky. The purpose of a firewall is to keep all unwanted data outside of your network. This means that the firewall will need to be configured to allow VoIP traffic. 

Ethernet Switches – It’s quite uncommon for an Ethernet switch to experience problems supporting voice.  However, VoIP telephones require external power. That power can be delivered via a local power source or through an Ethernet connection. To send it through a data connection, all you need to do is replace your present Ethernet switch with Power over Ethernet (POE) switches.
