What is the cause of ‘dropped’ calls (call ends unexpectedly)?

In general, "dropped" calls are the result of severe latency or packet loss in your Internet Service Provider's (ISP) network. In other words, for a period of time your connection may not be fast enough to send and receive voice data, resulting in lost information. This situation is called "Packet Loss".

Packet Loss may occur when connection speeds are compromised by temporary ISP problems, network congestion, or heavy bandwidth usage.

• Check a few web sites you commonly view and see if they are performing slower than usual. If this is the case, it is probable that your ISP is experiencing a problem. 
• If anyone is sharing your Internet connection, or you are uploading/downloading files via the Internet, pause this activity and see if voice quality improves

It is important to note that Othos strongly insists on a dedicated and/or optimized connection for voice in order to avoid such issues.
