Communication is a process through which information, ideas, thoughts and emotions are transferred from one location to another. The sender encodes the information and after it reaches the receiver, the information is decoded; this information may be carried through different channels of communication which are fully relied on for success in the sending process. Signalling systems in voice communication a set of telephony signalling protocols, they are used in the set up of most of the switched telephone calls in the world. They aim at setting up the and also tearing down telephones calls (Ronayne, 1986).

Channel signalling systems used in voice communication

In a multi-channel communication system, a channel for every link is used for signalling to account for, control and manage traffic on all the channels of the link. The signalling systems consist of line signalling and trunk signalling. Line signalling is a connection from local exchange office to a business telephone or a single-line telephone. Loop Start is the most common line signalling method used to communicate with single line telephone set. Ground Start is another that is more common on trunks and PBXs. Trunk signalling performs tear down and out-of-band call set up, it uses ISUP layer protocol. This truck system gives a chance to your subscribers to have virtually instant connections and also facilitates you to use full range of advanced network services; a good example is the Calling Name and TCAP class messaging (Russell, 2002).

Advantages

The ground start has the potential to minimize the possibility of glare by ensuring provision of remote-end disconnect supervision. They uses local number portability, facilitate number translation, short messaging services, prepaid billing mechanisms and various market services (Russell, 2002).

Disadvantages

The Ground Start tip and ring leads cannot be reversed. The in-band signalling is susceptible to frauds since toll thieves are in a position to defeat automatic systems by using devices that emulate signalling tones. The setup time is reduced by using a separate signalling network. The reduced time reduces the access charges to the LECs. In-band is also unable to support virtual networks which include credit card authorization and cellular phone roaming (Telecomservices, 2011).

Voice Processing Systems

This is a processor that is used in the streamline the state of the voice. The receptionist can be in a position to answer your call beginning with greetings which have been fed automatically. In most cases the voice calls are received by an auto-attendant, and after the set automatic greetings, the call is later directed to the appropriate individual or company. Voice processing system facilitates users to use their own personal greetings and at the same time listen to their calls by use of a different security code for each user, this is applicable at home in business or on the move. It facilitates recorded messages to be retrieved, sent and received at any time through any touch-tone telephone throughout the world (Telecomservices, 20

Advantage

This has come to help in the off loading the burden to the overworked phone call operators, you can transfer your messages and screen your calls to different colleague mailboxes. It makes sure that every client or customer is properly dealt with in a secure and decent manner. This system is also cheap, convenient and easy to use. It is also not necessary for both parties to be online for messages to be delivered, works for 24 hours a day, and fine tunes the voice calls.

 Disadvantages

The only disadvantage is that, the system looks technical for first time uses and this scares away some potential users.
