VoIP Quality Considerations

For many individuals, the benchmark of whether or not a particular VoIP installation is a success is the quality of the calls compared to what they are used to using the traditional PSTN phone system. This makes sense. After all, we shine only in comparison. Over the years, VoIP has gotten a bad rap for calls that experience jitter and latency. In the early days of the Internet, this truly was a problem due to the rarity of high-speed broadband as well as the relative newness of the technology itself. These days however, there is no need for a VoIP call to be any worse than regular phone calls and in many cases it is superior.

Unlike the PSTN phone system however, VoIP is not yet standardized. That means that there are several configurations and parameters that can affect call quality from installation to installation. In addition to this, there are indeed a few factors that can adversely affect the consistency of a VoIP call even today such as the distance the IP packet has to travel as well as the reliability of the Internet connection and not just the bandwidth.

Working with Your ITSP

Your SIP provider is the entity that best knows its own VoIP service. If you ask them, they will provide you with all the details you need in order to configure your clients properly. Which codecs to use, what kind of NAT traversal technique is best and a host of other configurations can all make a difference to how you experience a VoIP call. In certain circumstances, your SIP provider will have their own softphone client that comes preset with the optimal configurations that work with their service. Use these apps if you can in order to avoid hassle.

When it comes to reliable Internet connections, there is only so much you can do. If you have a standalone VoIP phone connected to the Internet via an ethernet cable, you will not notice any issues at all. Ethernet is stable, fast and reliable. These qualities are also shared by Wi-Fi to a slightly lesser extent but is more than ample for the meager requirements of VoIP. The danger of low call quality lies perhaps with the wireless data connections provided by the telecom companies. While 3G and 4G technologies have more than enough throughput in terms of bandwidth for VoIP systems, they still fall behind Wi-Fi in terms of reliability and consistency. But your mileage may vary.

It is also important to choose a local Philadelphia VoIP services provider in order to minimize the round-trip times of the IP packets. This decreases latency which can quickly become a key problem in any VoIP setup. Don't hesitate to get in touch with your ITSP to find out what you can do to improve the quality and what configurations are best.
