Voice over Internet Protocol (VoIP) is a way for people to communicate with voice, like a telephone, over the internet. VoIP can be quite tricky to get working right. Delay and choppiness in voice quality is quite regular. Knowing how to troubleshoot VoIP can drastically improve these issues.
- Communication over the Internet is sensitive to any type of delay. VoIP applications, such as Skype, require a steady stream of packet (bits of information transferred over the Internet) to run smoothly. If packets are somehow mixed up in transmission, some arriving early and some late, it can cause a jittery sound to the voice. If you use a VoIP phone, changing the model you have to one with a larger jitter buffer, a First-In First-Out (FIFO) memory cache, which collects any packets in order and delivers them in order, may solve this issue.
- If you are having problems with your VoIP client when using a VoIP application on your computer such as Skype, close any applications that you have open that may be using a lot of your computer's RAM. Random Access Memory, or RAM, is virtual memory that allows your computer to run at a quicker speed by remember application preferences once they are opened. Some applications use a lot of RAM; this can cause drag on other memory hungry applications, such as a VoIP program. Shutting down programs that you are not using, and sometimes restarting your computer, can make your VoIP quality drastically better.
- If you are experiencing problems with your VoIP network even after troubleshooting, you may need to consider purchasing a VoIP monitoring tool. These tools can analyze the packages coming into your system and tell you where the problem lies. Many programs are built for corporation class VoIP networks and can cost lots of money. Solarwind's Orion IP SLA Manager is a corporate level example of VoIP monitoring systems.
