There are more elements in a phone call than we can notice. There are many technologies involved in this communication process. It seems very simple to us, a phone call. However, the process is quite complex in nature and involves complicated technical things most of us are not aware of. Let us discuss some of them below.

There is a special feature offered by some telephone companies in Oceania and Europe which can be used for the private branch exchange system of their customers. This facility is known as direct inward dialing (DID) or direct dial-in. This term has its origin in the convention of telephone, as it let you reach the individual extension of a PBE directly through its standard outside number. In the modern day usage, such technologies are quite important for the telephone companies. These DID incoming numbers are something these companies work on.

It is only recently that the companies are using individual numbers to provide their subscribers with separate DIDs. This is the number the voice-over -IP providers generally refer to. If you ever go to a VOIP provider of Singapore, you can notice the use of DIDs as the VOIP Singapore number.

There is another technology called SIP Trunking, which is basically a VOIP working as a streaming media, providing services on the basis of the Session Initiation Protocol. With the help of this process the Internet telephone service providers can deliver satisfactory telephone services via a unified communication to all the customers who are equipped with SIP PBX. Such unified communication facilities are always welcome by the customers. Most of such unified communications software comes with applications which offer video, voice and other applications belonging to streaming media. For instance, web conferencing, desktop sharing, whiteboard sharing etc. Many telephone companies these days look for a good SIP trunk service provider.

The SIP trunk service has a particular form of architecture which provides a partition between the two main domains of the unified communications network. According to expertise these domains are Private domain and Public domain.

Private domain: It refers to a VOIP solution set up at the customer’s home that can derive advantage of the phone and the services of the unified communication network.

Public domain: This refers to all full VOIP solution with access to the PLMM/PSTN property of the ITSP. It also undertakes the responsibilities along with it and provides the phone service.

Such complex mechanisms ultimately make a phone call possible. This is why the telephone service providers generally opt for such services. The connection strength depends upon the proper workability of these services put together. A customer must always prefer an undisturbed connection while talking over a telephone. There are several other reasons why these technologies are quite popular with the customers. For example, the DID Service helps connecting one or more PBXs of the customers through several trunk lines. This is a significant the group reason why this service is preferred.

Good telephone companies give much priority to such services and see to the fact that these services are dealt with properly.
