VOIP Problems
Voice over internet protocol (VOIP) is changing the way that the average consumer makes long distance phone calls. The technology is rapidly
advancing because companies all over the world are now competing to be your VOIP provider. However, there are still VOIP problems - especially
when it comes to using the technology for functions beyond the one caller to one caller scenario. VOIP problems can be annoying, but are
relatively limited for the consumer.
The main complaints regarding VOIP have to do with providing the level of quality of service that customers are accustomed to with regular
telephone technology. The reason for this is multifold. VOIP requires a large amount of data to be compressed and transmitted, then uncompressed
and delivered, all in a relatively small amount of time.
Problems develop in VOIP conversations when this process takes too long and the callers experience one of two problems; echo or
over-talk. Standard phone calls function with a delay of no more than 10 milliseconds. But VOIP problems have led to delays of up to 400
milliseconds, meaning that the callers won't hear each other fast enough to make the conversation flow easily.
They will either hear themselves talking or they will start talking again before they have heard the other person respond. Although these
problems won't necessarily happen every time a call is made, it can happen often enough to be annoying.
These VOIP problems are usually tolerable if the callers are using a free service such as skype.com, and the calls are for individual,
personal communication.
But once a network of users, such as a business, wants to use VOIP, the problems become a little more complicated. Part of the reason is that
most networks have a firewall; and most firewalls don't know how to route a VOIP call once it is received - which phone does it go to?
Plus, multiple users create a problem when judging what amount of bandwidth can be and should be used at any time. If multiple users need to
make VOIP calls, it can be difficult for the company to know exactly how much bandwidth to provide - especially if internet access, video
conferencing or other data transmission services are using the same path.
Overall, VOIP problems aren't significant enough to dissuade the average consumer from using the technology; especially with the fact that
they know that the calls they are making are free. But we can rest assured that the technology will only get more reliable as time goes by.
