What Can You Do to Improve Your VoIP Performance?

Communication Management at the Client Side

One of the major differences between VoIP and the PSTN network, is that the former requires a certain amount of management by the customer. This isn't to mean that the traditional telephone network requires no management at all. It does. But over the decades, all that has been abstracted from the customer. In addition, the PSTN system makes use of circuit switching which ensures that once the call is connected, no other activity on the network can effect it because it is a dedicated line. The Internet however make use of packet switching which lies on every communications link being utilized to its full potential. This means that several streams of data can work on it at the same time. While this makes for excellent efficiency, it can lead to problems when our network data interferes with a real-time VoIP protocol.

However, it easy for users of VoIP to take a few precautions to ensure that they get the best possible clarity and speeds from their SIP provider. It all starts with the management of your Internet network. The first thing to do is to ensure that other network activity does not interfere with the bandwidth that you have dedicated VoIP. Other web protocols like HTTP are extremely resilient when it comes to delays. Moreover, users expect somewhat jittery performance when loading websites. But when talking to another person, even a delay of a few tens of milliseconds can make it impossible to speak clearly.

Network Management and SIP Settings

Both home users and business customers should ensure that they have a VLAN set up. What this means is that they create a virtual network for all VoIP traffic – sealing it off from everything else. Then even if someone on the network is downloading a huge file at maximum speed, there will always be enough VoIP bandwidth remaining for smooth communications. This bandwidth limit has to be modified from time to time as your business grows and more and more users are added to the network.

The second thing you can do is optimize your SIP settings to ensure maximum efficiency. The best thing is to contact your ITSP and find out what settings they recommend for your particular SIP client. If your SIP provider provides their own client, that's great! They will always be optimized to work with your VoIP service. But if you're using a third-party SIP client, it's important to ensure that you're using the proper HD voice codecs, and have set up all the other parameters properly. If you stay in Boston, you can contact a Boston PBX VoIP provider and get started in as little as 15 min.
