The Intelligent Network service of lines 900 is free for the call issuer, that is, the cost is paid in its entirety by the contracting company with NUINTESA. This kind of service is very useful as a marketing tool, as it facilitates the access to new costumers as well as improves the dimension and image trademark of the companies.
Lines 900 stimulate both information requests and the realization of more calls than geographical telephony may receive. Like the rest of Intelligent Network services these phone lines may be diverted to as many geographical numbers as clients may desire. This is recommended for those Great Companies or Public organisms which first pursue the facility of access for the call issuer.
