.Corporate RBT is a new service provided by Irancell's Enterprise Business Division for companies and organizations which enables them to set an RBT to be played on their staff cellphones with due regard to the company's marketing needs. By means of RBTs, companies can introduce the nature of their business while promoting their brand.
In this way, companies set their own customized RBTs on all their staff's Irancell numbers so that when customers call any of the staff they hear an advertising message, which can be in the form of a song or merely a voice giving some information about the company.
