New telephone technology is replacing the old landline systems which are slowly becoming obsolete largely due lower cost options like high quality VoIP calls. VoIP systems are the new breed in communications technology, making waves in the telecom industry. Its scalability, reduced costs, easy installation and maintenance is providing business owners options to consider for their phone line communications.  But are these new systems as reliable as the traditional phone line service?

All technology in its infancy is plagued with minor issues, bugs and glitches that need rectifying. New software improves as times goes on and hardware such as telephones do as well, in the early days, telephones also had their fair share of problems with call drop outs and sound quality problems. VoIP call technology is very reliable and although it’s in the early stages of advancements, common issues are easily diagnosed and corrected.

We want to help you get a grip on your call issues, so let’s take a look at how to improve your VoIP call quality!


Jitter is one of the more common problems that exist with VoIP calls. Voice information is divided into data packs and sent between sender and receiver. These packs can reach the receiver scrambled and that will often degrade sound quality as the packets are time sensitive.


Jitter Buffer is a temporary storage buffer which essentially holds the arriving packet and keeps its order to help reduce the sound degradation caused by packet time variation.   



Latency is the time interval of the conversation between speaker and listeners. Speech takes time to travel and its delay is called latency which causes an annoying echo that needs to be dealt with.

Three types of latency issues

  1. Propagation delays: Occur in very long distance calls when the head of the signal needs to travel over wire from sender to receiver. These delays are barely noticeable but in conjunction with other delays it can degrade the quality of the call.
  2. Handling delays: Occur from network technology devices.
  3. Queuing delays: Occur when packets are held up in queue and more packets are sent than the interface can handle.


A solid network infrastructure is your secret weapon in latency. A quality VoIP router should handle many of these issues and an edge device will provide features to handle all packet prioritization. An edge device is an appliance that provides unique features to reduce delays and ensure robust voice packetization.

Internet Connection

Common internet connections are not designed to meet the protocols of today’s VoIP. A high speed internet connection can resolve many of the issues related to internet connection problems and with a high quality VoIP provider you’ll be on track to ensure your business starts utilizing high quality VoIP calls.  


Solution is to use a provider with business class high speed internet connection.

Router Problems

VoIP routers prioritize data traffic, an essential feature which standard routers lack. The possibility of other users on the same network to interfere with the router's ability to perform tasks is very likely and without a packet prioritization the quality of call can be affected.


VoIP routers are an essential tool for your business and choosing a correct router that meets the requirements of your network will allow your VoIP calls to run smoothly.

Network Configuration Problems

If both voice and data are sent over the same network and you lack the necessary configuration of equipment you can expect poor quality calls.

Understanding issues with VoIP call quality will allow you to diagnose and follow them up with the necessary protocols to correct them. VoIP technology will soon become the norm and managing many of these inconveniences will be simple tweaks. Ensuring you have the best VoIP provider and have tackled the above issues you’re set to provide your business with high quality VoIP calls and features.
