IP telephony is the latest communication technology. It uses internet protocol connections to transmit voice calls, fax and other types of communication data over a network. The Public Switched Telephone Network is the communication network that has been around for a long time. It uses dedicated circuit switched connections to transmit voice calls and faxes.
In the IP telephony technology, the voice calls and other form of communication are converted into data packets before being transmitted over the network. The charges differ, since the mode of transmission is not the same as that of the public network. The IP telephony has some disadvantages. Some of them have been highlighted below.
First of all it is not dependable. A lot of data is lost while being transmitted from one point to another. This leads to poor communication or hinders communication completely. Delivery is also not sequential and sometimes the messages end up getting jumbled. This type of communication is also affected by power shortages. This is because most of the transmitters and receivers rely on electricity to operate. Due to this, many people prefer the analogue phones since they are more reliable and are not affected by electricity shortages.
It is also difficult to locate the geographical location of a network user when using Voice over Internet Protocol (VoIP). This makes it difficult to locate where emergency calls are being made from, therefore hindering rescue efforts. In addition to this, internet outages, just like power black outs, normally paralyze IP telephony. This also prevents the authorities from responding to emergencies effectively.
This type of communication technology also has its advantages. First of all it is far much cheaper than the public switched telephone network. This is because the initial cost of setting it up is very little and the running costs are also minimal since it relies on the internet to operate.
Finally, it is more flexible. It can perform some tasks and offer services that are difficult to implement using the PSTN.
