Number Presentation, also known as Pre Call Display, provides you with the number that your caller has dialled before you answer to call.
This feature allows you to know if the call has come from your marketing number.
You can edit this to show your marketing number or even your company name on your phone handset.
How this helps you
This service allows you to answer your phone calls in a professional manner, knowing that the call is business related.
This is useful if you use your phone for both business and personal calls and want the ability to answer the calls correctly.
