VoIP Phone Systems and Some Ways
to Improve Call Quality
 Be sure to opt for private VoIP service. You may certainly be able to save some money when opting
for public VoIP services, but you are not going to get good quality. Private, dedicated networks are
going to perform much better.
 Use high quality cables. Cutting corners can significantly affect the call quality. You are likely to face
fewer issues in this regard when you opt for CAT-5 cabling, as it is fast enough to manage VoIP
traffic.
 Pay special attention to network monitoring. The best thing is to take advantage of your service
provider's network monitoring service to handle packet loss and jitters in a better way. This will
directly affect the overall call quality.
 Be careful when allocating bandwidth. This is another aspect where many people make wrong
decision and end up compromising the quality of calls. It is best to keep data and voice traffic
separate with the help of a VLAN. You can also take advantage of non-blocking switches, as they
help prevent packet loss and collision. Be sure to use network analysis tools to know that
everything is working fine.
 Make use of echo cancellation hardware. You can invest in VoIP hardware, IP PBX, and handsets
with echo cancellation feature. This may require a greater investment, but you will notice a
considerable improvement in the overall quality of your calls.
 Consider upgrading your network suit for better results. You may think that you can manage
everything with your existing networking monitoring and management suit, but you will be better
off upgrading it to accommodate VoIP.
