Direct Inward Dialing (DID) numbers are virtual phone numbers (also known as SIP trunk numbers) that enable you to route calls to your existing telephone lines. DID numbers are used to assign direct numbers to specific members in the team, without the need of multiple physical telephone lines. They are phone numbers with intelligence that can help you manage calls the way you want to.
The simplest way that businesses make use of DID numbers in India, is to route incoming customer calls. When a customer calls the business, they hear an IVR greeting that asks them who they want to speak to and forwards their call to the right agent based on their inputs.
DID numbers makes it easier for business to monitor the calls for performance analysis – track the number of calls missed, the turnaround time of an agent, time spent on call and customer call recordings.
