Direct Inward Calling
Direct inward calling (DID) can be a special service that telecommunication companies offer to a private branch exchange system (PBX). This system allows companies to use different numbers for different parts or offices. This allows companies to have different numbers for different parts of the office from the same machine. The customer can call the person they need to resolve their problem if they use this service. This is important for any business because it saves customers time and ensures satisfaction.
An example of an inward dialing system can help to better understand it. Consider a company that has hired a telecom company with eight trunk or physical lines. It has rented 100 phones from this company. Because it has eight trunk lines, it can receive up to eight calls simultaneously. All others will get a busy message. These people can leave a message or wait until the call is disconnected. This would lead to low satisfaction levels and could prove dangerous if customers are even slightly impatient. The company can use a DID system to automatically divert calls to the right operator or workstation if it has one. This saves time as no additional PBX operator will be required.
