Call channels are like virtual phone lines - if you receive an inbound call and make an outbound call this will use a call channel. The evolution of call channels has undergone a transformation over the years, as we've moved from traditional analogue systems to modern digital and Voice over IP (VoIP) technologies.
Examples of Call Channels
Analogue Telephone Lines and Single-Channel Calls
Traditional analogue telephone systems in the early days operated on a single call channel, which means they were only capable of handling one voice call at a time. This meant that when a line was in use, the user had to wait until it was available to make a call.
Digital Telephone Lines, TDM Technology, and Voice over IP (VoIP)
The transition to digital telephone lines meant that transmission for multiple calls over a single communication channel was allowed. This was possible due to time-division multiplexing (TDM) which divided the transmission time into discrete time slots, each allocated to a different call. After this, Voice over IP (VoIP) was introduced which enabled voice communication of the Internet Protocol (IP) which utilised packet-switched networks instead of dedicated physical channels.
Call Wait and Call Holding
These types of features allow users to manage multiple calls on a single line or channel. For example, if you have an incoming call whilst already on a call, you could temporarily set aside one call to answer the other.
Video Calls and Conferencing
Call channels can also be used in a broader context of other communication methods to describe other forms of real-time communication.
Why are Call Channels Important?
Increased Capacity = Call channels allow multiple calls to occur at once, which is important for businesses and call centres that need to handle a large volume of calls simultaneously. In particular, if there are urgent matters to resolve, this can be done quickly and efficiently.
Various Communication Modes = Call channels support a variety of communication modes, including traditional phone calls, video calls, and conferencing. This flexibility allows users to choose the most suitable and preferred method of communication for their needs.
Enhanced User Experience = Multiple call channels reduce waiting times, allowing a better user experience. Callers are connected more quickly, meaning their issue is resolved quickly, and they leave with a higher satisfaction level.
