Possible VoIP issues Drop or jitter in VoIP audio can be cause by a number of different things. Some of the possible issues that could cause a drop in audio include connections issues, bad packet routing, malfunction session timers, over aggressive silence detection, or talk-off's. Any one of these can be a cause of dropping audio in a VoIP call. Some may happen more frequent the others and some may be more severe, but understanding all possible issues can help determine the cause when troubleshooting issues (Smartvox.co.uk, 2013). Connection issues, not only limited to inside the VoIP system is probably one of the biggest causes of dropped audio. If your ISP is experiencing connection issues than the quality of your VoIP connection will

The SIP protocol requires the packets to be received in a timely manner. If the routers are routing packets and taking longer than normal it could completely drop the call as the protocol has timed out. This is also the same issue whit malfunctioning SIP protocol timers. The timers are in place to end calls if the connection has been disrupted before the end of call packet has been sent in order to terminate the call. If this timer is malfunction it may think that it should have received a signal and prematurely end the connection (Smartvox.co.uk, 2013). Finally you can be affected with and over aggressive silence detection. Once again this is a feature that will terminate a connect should the server think a long period of silence is a sign that the connection has ended. This can help terminate connections that are truly ended, but can also cause the call to drop unexpectedly. Finally you come to talk-offs, this is when the server misinterprets the person talking as machine or modem communication sounds. While it may not always call the call to drop audio there is the possibility of it occurring (Smartvox.co.uk, 2013).

This could be your router, firewall, or even on your ISP side of the connection. This has helped you eliminate other areas narrowing down the overall issue with the connection. Since VoIP is a network connection, any packet tracking software will help in troubleshooting connection issues. There are a number of freely available tools such as Wireshark, Capsa, Microsoft network monitor and even and old tool called tcpdump. All of these tools will capture the packets traveling on your network. If you capture them from different points on your network you can determine where the issue is occurring. Wire shark can show if the packets from a connection are able to reach the server or if and where they are being blocked (Rubens, 2013).
