We all love to keep in touch with our loved ones and most of us are nearly dependent on telecommunications when it comes to our jobs. We use them to keep track of progress, for purchases, to search for information, find potential clients and so on, but when it comes to the costs of these services that are so vital to us we would all like to have the best deals. There are a few options out there that can fit our needs but the most popular lately has become the communication form based on the VoIP PBX dependency. VoIP uses a protocol called SIP or Session Initiation Protocol to control the communication sessions, but it is the PBX that creates the internal network for any company or larger group that use this service. The VoIP PBX relation can be used in places were an internal network can be useful like a large corporation or even an apartment complex that uses the same provider.  SIP trunk is the service that allows you to experience more than one session simultaneously, thus granting access to all user at once if necessary. The SIP protocol mentioned earlier is the type that controls the communication sessions and the trunk of a SIP trunk can contain multiple voice sessions.

          A very important feature of the SIP protocol in the SIP forking. A more elaborate explanation of the term would be that this feature allows a single call to reach multiple SIP endpoints like your mobile and desk phone at the same time. Forking also allows the feature that can most often be seen in movies, of a secretary taking the call from the bosses office when he’s not in or otherwise busy.

          Depending on how much a company is willing to invest in the transition to the VoIP system, a business can have the components and equipment installed on site or may chose to use the hosted VoIP option and place the management of the network in the hands of a provider that specializes in VoIP hosting. In truth hosted VoIP is rather recommended if the corporation is reluctant to invest in the equipment required for the system, since the amount of money that needs to be spent on it is usually what makes companies adopt this system. However, if you choose to opt for hosted VoIP do so with the knowledge that if your internet connection is lacking in quality there may be some jitters or latency. So before you decide make sure to upgrade your internet connection as well.

          So keep in mind that the VoIP PBX relation is dependent on the SIP trunkwhich in turn is based on the SIP protocol, but the entire network relies on a good internet connection, good and functional servers and power supply. Take any one of them away and the whole network will stop working.  Since this is common knowledge among hosting providers, it is generallyrecommended for companies to subscribe to one, since they are prepared for this type of situations.
