The American company, Slydial, gives the opportunity to subscribers to avoid uncomfortable conversations by phone. Henceforth, the subscriber can leave the message as a voice mail even if the intended phone is on and is in the coverage zone.
For this purpose, the one wishing to avoid a conversation should dial the service number and then the number of the person. The service is paid through small advertising which the user listens before connection. There is also possible to skip the advertising by paying 15 cents for the call.
As a result, the interlocutor will receive a “new message” notice. However, in some cases he may see a missed call.
