As VoIP phone systems operate in a different way to that of traditional circuit switched analogue phone systems, the cost structures can be very different.
For applications like Skype where Skype to Skype calls are made there is no cost associated with the sale. Although if calls are made to a landline or mobile with a number over the telephone network, then there is a cost. Other similar applications use a similar model for charging.
For VOIP business phone system Doha Qatar systems where special VOIP business phone system Doha Qatar are used and a number allocated, there are a variety of different charging structures. This will depend on the particular telecommunications VoIP provider.
The traditional circuit switched charging structures tended to charge more for longer distance calls. The reasoning behind this was that longer stance calls utilised more circuits and therefore there was significant logic to this. With a VoIP phone system the situation is different and VoIP providers are starting to reflect this in their structures.
Some allow local calls free, others include country-wide calling, or state wide-calling in the basic cost plan. Other allow a certain number of minutes, etc. It is best to check on what the different available VoIP providers offer and make a decision based on the most cost effective operation for the given situation.
How does VoIP work
Digital technology is at the heart of VoIP phone systems and enables them to be used for business phone systems as well as for smaller installations as well.
VoIP (voice over IP) is the transmission of voice and multimedia content over Internet Protocol (IP) data networks. VoIP is enabled by a group of technologies and methodologies used to deliver voice communications over the internet, enterprise local area networks or wide area networks.
The concept of Voice over Interent Protocol, Voice over IP, or VoIP, is quite straightforward. A VoIP system basically consists of a number of endpoints which may be VOIP business phone system Doha Qatar, mobile phones, VoIP enabled browsers on computers, etc and also an IP network over which the packet data is carried.
In a VoIP system, the phone or computer acting as an endpoint consists of a few blocks. It includes a vocoder (voice encoder / decoder) which converts the audio to and from the analogue format into a digital format. It also compresses the encoded audio, and in the reverse direction it decompresses the reconstituted audio. The data generated is split into packets in the required format by the network interface card which sends them with the relevant protocol into the outside world. Signalling and call control is also applied through this card so that calls may be set up, pulled down, and other actions may be undertaken.
The IP network accepts the packets and provides the medium over which they can be forwarded, routing them to their final destination.
Both ends of the communication will have distinct IP addresses and this enables the data packets to be correctly routed between the two phones.
As complete circuits are not dedicated to a single user as in the case of analogue circuit switched networks, at times when no data needs to be sent, for example during quiet periods in speech, etc, the capacity can be used by other users. This makes a significant difference to the efficiency of a system, and allows significant savings to be made.
Traditionally the term VoIP referred to systems where IP was used to connect private branch exchanges, PBXs, but now the term is more widely used and encompasses IP Telephony PBX PBA Doha Qatar.
