How Does a DID Number Work?
The main distinction between a physical phone system and a virtual phone system is that virtual systems make use of an already existing phone, so businesses do not have to specially purchase, install, or maintain expensive phone hardware. All you need is a reliable DID number provider and one main DID number, while employees are assigned their own respective extensions.
Thus, when a customer contacts your company by dialing its business line (DID number), the IVR answers the call. Then, it transfers the caller to the extension of the desired employee or department.
A potential customer can contact a DID number in one country. And when the call forwards, they may end up conversing with an individual in a completely different country. This way, DID numbers make communication widespread and affordable.
