The advantages of IP telephony

Those who decided to experience all the benefits of IP telephony, supplied before choosing the right voip gateway. First of all, it should be noted that the use of such equipment is very beneficial, because you don't have to change all the telephones in the network. You will be able to organize IP-PBX based on the existing analog network. Every year more and more companies prefer IP-telephony and communication, so manufacturers produce a huge number of models. It should be noted that some devices are not compatible with those or other analog devices, so before buying it is necessary to clarify a set of standards that supports one or another voip gateway.

This unit is a infrastructure equipment, which will have a number of features. First of all, it is a physical limitation in performance. So, if the data network is increased and there is more productive equipment, with regard to IP telephony, via a single analog port can connect only one line with one link.

When choosing this type of equipment, consider the type of cooling and installation requirements. One of the main advantages of IP telephony is that the voip gateway can be installed as close as possible to a telephone. But it is worth noting that the closer the fixture is to be installed, the requirements must be met. This applies primarily to cooling.

Special attention is given the build quality. Often manufacturers skimp on the plastic, which is made of the case. This can lead to negative consequences. The poet is best to choose a model with a steel body. So, when reset, will deteriorate to the device.

One of the most important factors when choosing a voip gateway is a DSP. As a rule, during testing of the equipment takes place in the "sterile conditions". When we are talking about real conditions, there is the echo and all sorts of extra noises. The reason is not that you're using the wrong machine or the wrong codec, and in the ip gateways and processors. How powerful and efficient processor installed in this type of equipment depends on its ability to convert a RTP stream that comes from IP, digital or analog signal of the synchronous flow. From these characteristics directly affect the voice quality.

Also, note the presence of features of echo cancellation, noise reduction, determination of pauses, the level control signal. Previously, these functions were assigned to the telephone station, and now they are fitted with terminals.
